Changing passwords is not necessarily bad; in fact, it is often recommended for maintaining good security practices. However, there are a few reasons why some argue that constantly changing passwords can have negative consequences. Here are some points to consider:
1. Password Fatigue: Frequent password changes can lead to password fatigue, where users struggle to remember new passwords and end up using weak or easily guessable ones. This defeats the purpose of improving security if users resort to predictable passwords.
2. Factoring Human Behavior: People tend to reuse passwords across multiple accounts since it’s easier to remember a few variations. With frequent changes, users may be more likely to use the same or similar passwords across different accounts, increasing the risk of a security breach.
3. Weakened Security: When passwords are changed frequently, users might resort to making small variations to their existing passwords, such as adding a number or changing the order of characters. This makes the passwords easier to guess based on previous patterns and reduces their overall strength.
4. Lack of Two-Factor Authentication (2FA): A more effective approach to improving security is to enable two-factor authentication (2FA). This provides an additional layer of protection by requiring users to provide a second form of authentication, such as a fingerprint or SMS code, in addition to their password. With 2FA enabled, changing passwords less frequently can be justified as the extra layer of security compensates for it.
5. User Education and Awareness: Instead of solely focusing on password changes, it is crucial to educate users about creating strong and unique passwords, implementing 2FA, and recognizing phishing attempts. These measures can go a long way in enhancing overall security without solely relying on frequent password changes.
In conclusion, while changing passwords is not intrinsically bad, there are some valid concerns regarding its effectiveness as a standalone security measure. Employing a multifaceted approach, including educating users about strong passwords and implementing two-factor authentication, can provide better overall security.

Why should you not change your password every 90 days?
Changing passwords regularly has long been a standard security practice. However, the notion that passwords should be changed every 90 days is no longer universally recommended. Here are the reasons why changing your password every 90 days may not be necessary or even beneficial:
1. Increased likelihood of weak passwords: Frequent password changes often lead users to choose weaker and easier-to-remember passwords. When forced to update their passwords frequently, users often rely on minor variations or slight modifications that can be easily guessed or cracked, undermining the goal of improving security.
2. Difficulty remembering complex passwords: Modern security guidelines emphasize the importance of using strong, unique passwords for each online account. However, generating strong passwords that are not easily guessable or crackable can make them harder to remember. Frequent password changes exacerbate this issue and can result in users resorting to writing passwords down or using insecure methods to remember them.
3. Minimal security gain: Continuous password changes mainly protect against an attacker who has access to an old password but not the current one. In reality, most successful hacking attempts occur through other means, such as phishing attacks, malware, or database breaches. These attacks render regular password changes less effective in preventing unauthorized access.
4. Two-factor authentication provides stronger security: Instead of relying on frequent password changes, implementing two-factor authentication (2FA) significantly enhances account security. By requiring a second form of authentication, such as a fingerprint or a unique code generated on a separate device, even if the password is compromised, the additional factor adds an extra layer of security.
5. Password managers offer better security: The use of reliable password managers is now widely encouraged. These tools securely store complex and unique passwords for all your accounts, eliminating the need to remember them. Leveraging a password manager can help mitigate the risks associated with frequent password changes by enabling the use of strong, unique passwords without the burden of memorization.
In conclusion, the commonly promoted practice of changing passwords every 90 days is no longer considered necessary or beneficial in most cases. Instead, focus on creating strong, unique passwords, employing two-factor authentication, and utilizing a password manager to enhance the security of your online accounts.
Does NIST recommend not changing passwords?
The National Institute of Standards and Technology (NIST) has indeed updated its guidelines regarding password security, shifting away from the traditional recommendation of regularly changing passwords. Here’s a breakdown of the reasoning and steps:
1. NIST’s updated guidelines: In recent years, NIST has revised its password security recommendations to emphasize more practical and effective measures. The previous practice of frequently changing passwords was found to have limited security benefits and often led to weaker passwords being created. Therefore, NIST now suggests focusing on other security measures that can yield better results.
2. Longer and stronger passwords: Instead of enforcing regular password changes, NIST advises using longer and stronger passwords. By increasing the minimum password length requirements and allowing the use of passphrases, users can create more secure and memorable passwords that are less prone to brute-force attacks.
3. Multi-factor authentication (MFA): The updated guidelines strongly advocate for the use of multi-factor authentication. This additional layer of security provides an extra barrier beyond a username and password, making unauthorized access significantly more challenging. MFA can include factors such as biometrics, SMS codes, or hardware tokens.
4. Monitoring breached password databases: NIST recommends organizations to implement systems that can check if passwords used by their users have been compromised in known data breaches. By regularly checking for compromised passwords, organizations can prompt users to change their passwords or take appropriate actions to mitigate risks.
5. Continuous monitoring and risk assessment: Rather than solely relying on periodic password changes, NIST encourages organizations to continuously monitor user accounts for suspicious activities and employ risk-based approaches. This involves analyzing user behavior, detecting anomalies, and taking action accordingly to protect against unauthorized access.
By updating its password guidelines, NIST aims to improve overall security while providing more practical and manageable recommendations for users and organizations. Emphasizing longer, stronger passwords, MFA, and continuous monitoring can better safeguard against unauthorized access and adapt to the evolving threats in the digital landscape.
What are the risks of password rotation?
Password rotation, the practice of regularly changing passwords, has been a common security measure for a long time. However, recent studies and expert opinions suggest that traditional password rotation may not always be the most effective approach. From a professional point of view, let’s discuss the potential risks or drawbacks associated with password rotation:
1. Weakened passwords: Frequent password changes often lead to users creating weaker passwords or using patterns that are easy to guess. This happens because it becomes difficult for users to remember multiple complex passwords, leading them to choose simpler and predictable variations. Weaker passwords increase the vulnerability of user accounts to brute force attacks or unauthorized access.
2. Resistance to change: Regular password rotation can frustrate users and lead to the development of poor security practices. Users might resort to writing passwords down, storing them insecurely, or using similar variations across multiple accounts to cope with the constant changes. These behaviors undermine the goal of enhancing security.
3. Synchronization complexities: Password rotation often requires users to update passwords across various accounts and devices. This task can become confusing and time-consuming, potentially leading to errors and security vulnerabilities. Users may also unknowingly reuse old passwords when rotating, inadvertently reducing security.
4. Lack of security in other areas: While password rotation may be seen as a robust security measure, it is important to remember that it only protects against one particular threat – the compromise of a stored password. Other security measures like two-factor authentication, secure network connections, and regular software updates are equally crucial and should not be neglected.
5. Neglected detection mechanisms: Frequent password changes might give users a false sense of security, diverting attention away from more essential security measures. Organizations should emphasize implementing and monitoring strong intrusion detection and prevention systems, as well as staying updated with emerging threats and attack vectors.
6. Increased support costs: Regular password changes can lead to an increase in support tickets and helpdesk requests, as users are more likely to forget their new passwords or encounter issues related to frequent rotation. This added burden on IT support staff can strain resources and impact overall efficiency.
To mitigate the risks associated with password rotation, organizations should consider adopting alternative security practices such as:
– Implementing multifactor authentication (MFA) to reinforce login security.
– Using strong password requirements during initial password setup to encourage the use of complex and unique passwords.
– Educating users about password best practices, including the use of password managers.
– Monitoring and alerting for suspicious activities and possible security breaches.
– Regularly updating and patching software to minimize the risk of vulnerabilities being exploited.
By taking a comprehensive approach to security and considering the potential risks of password rotation, organizations can ensure a balance between strong security practices and user convenience.
Does changing password remove hackers?
Changing your password alone does not completely remove hackers from your system. While changing your password is an essential first step in protecting your online accounts, it is not a foolproof solution against hackers. Here are a few key reasons why changing your password does not immediately remove hackers:
1. Persistence: Hackers can use various methods to maintain access to your system even after the password is changed. They may have installed malware, backdoors, or other malicious software that allows them to regain access easily.
2. Multiple Attack Vectors: Hackers can use various attack vectors apart from password cracking. They might exploit software vulnerabilities, use phishing attacks, or target weak security protocols to gain unauthorized access to your system. Changing your password alone does not address these other vulnerabilities.
3. Unauthorized Access: If a hacker has already gained access to your system, they might have already compromised other critical accounts, installed keyloggers, or created additional user accounts with administrative privileges. Changing your password in this scenario does not guarantee that the hacker’s activities have been completely stopped.
4. Persistence through Persistence through Persistent Threats: Advanced persistent threats (APTs) are sophisticated hacking techniques where attackers intentionally maintain a long-term presence in a targeted system. In such cases, changing your password is not enough as APTs are designed to withstand changes and remain undetected.
To better protect yourself against hackers, it is crucial to follow these additional steps:
1. Enable Two-Factor Authentication (2FA): Enabling 2FA adds an extra layer of security where you need to provide a second form of verification, such as a code generated on your phone, when accessing your accounts. This makes it significantly more difficult for hackers to gain unauthorized access even if they have your password.
2. Update and Patch Your Software: Regularly update your software and applications to ensure you have the latest security patches installed. Vulnerabilities in outdated software can be easily exploited by hackers.
3. Use Strong, Unique Passwords: Create strong, unique passwords for each of your online accounts and consider using a reliable password manager to securely store and generate complex passwords. This prevents hackers from easily cracking your passwords.
4. Be Cautious of Phishing Attempts: Be vigilant when opening emails or clicking on links. Phishing attacks are a common method hackers use to trick users into revealing their credentials or downloading malware. Verify the authenticity of the sender before sharing any sensitive information.
5. Monitor Your Accounts: Regularly monitor your online accounts for any suspicious activities or unauthorized access. If you notice any unusual behavior, report it immediately and take steps to secure your account.
By adopting a holistic approach to security and regularly evaluating your online habits, you can greatly reduce the risk of being compromised by hackers.
Is it good to have different passwords for everything?
Yes, it is highly recommended to have different passwords for each of your online accounts. Here’s why:
1. Security: Using the same password for multiple accounts puts all of your accounts at risk if one of them is compromised. If a hacker gains access to one account, they can easily try the same login credentials on other websites or services, potentially gaining unauthorized access to your personal information, financial data, or even social media accounts. Having unique passwords for each account significantly reduces this risk.
2. Protection against password breaches: Password breaches are quite common, where large databases of user credentials are stolen or leaked. Hackers then attempt to use these credentials to gain unauthorized access to various accounts. Using the same password makes it easier for attackers to exploit this situation. However, having different passwords ensures that even if one of your accounts is compromised through a breach, your other accounts remain secure.
3. Complexity and strength: When using different passwords for every account, you have the freedom to create unique, strong, and complex passwords for each one. Strong passwords usually consist of a combination of letters, numbers, and special characters, making them harder to guess or crack using brute-force attacks or automated hacking tools. By using unique, complex passwords, you increase the security of each account individually.
4. Password managers: Managing different passwords for each account can be challenging, but password manager applications/software can help ease this burden. These tools securely store your passwords in an encrypted vault, allowing you to generate and retrieve strong, unique passwords for each site without having to remember them all. Password managers can also provide added features, such as automatic form filling and secure password sharing.
5. Two-factor authentication (2FA): Even if you have unique, strong passwords for each account, enabling two-factor authentication adds an extra layer of security. 2FA requires an additional verification step, usually through a text message, email, or authenticator app, along with the password. This ensures that even if someone manages to obtain your password, they still need physical access to your secondary device or a unique code to complete the login process.
In summary, having different passwords for each of your online accounts is essential for maintaining strong security practices. Unique passwords protect your accounts against breaches, increase the complexity and strength of your passwords, and help you manage your online security more effectively. Additionally, utilizing password managers and enabling two-factor authentication further enhances your overall online security posture.
Does changing your password get rid of hackers?
Changing your password is an important step in bolstering your online security, but it does not guarantee that hackers will be completely eliminated. Here is a professional perspective on why changing your password alone might not be sufficient to get rid of hackers:
1. Multiple attack vectors: Hackers rely on various methods beyond just obtaining your password. They may exploit vulnerabilities in software, use social engineering techniques, or employ other means to gain unauthorized access to your accounts or devices. Changing your password won’t mitigate these other attack vectors.
2. Stolen credentials: Hackers often obtain login credentials through data breaches, phishing attacks, or malware. If your password has been compromised and is already in the hands of hackers, changing it won’t retroactively protect you. They may still be able to access your accounts using the stolen credentials.
3. Weak passwords: Many users tend to create weak passwords that are either easy to guess or reuse across multiple accounts. Even if you change your password, if the new one is weak or easily guessable, it won’t provide strong protection. It is important to create strong, unique passwords for each account.
4. Advanced hacking techniques: Hackers continuously evolve their methods and employ advanced techniques to bypass security measures. They may use tactics like keyloggers, brute-force attacks, or exploit zero-day vulnerabilities. Changing your password alone may not be enough to prevent such sophisticated attacks.
To enhance your security and minimize the risk of being hacked, consider the following additional measures:
– Enable multi-factor authentication (MFA) wherever possible to add an extra layer of security.
– Stay vigilant for phishing attempts and be cautious about sharing personal information.
– Regularly update your devices and applications to patch security vulnerabilities.
– Maintain strong, unique passwords for each account and consider using a reputable password manager to securely store them.
– Use security solutions like antivirus software, firewalls, and secure networks to protect against malware and intrusions.
– Educate yourself about current security best practices and stay informed about the latest threats and security updates.
Remember, cybersecurity is a continuous effort, and implementing a multi-layered approach is crucial for effective protection against hackers.
