The NIST guideline recommendation for passwords has become a vital reference point for enhancing digital security in a world where password breaches are increasingly common. NIST, or the National Institute of Standards and Technology, plays a critical role in shaping cybersecurity standards for federal organizations, private sectors, and individual users. The latest revisions to their guidelines, known as NIST Special Publication 800-63B, highlight key improvements to password creation, management, and authentication. These updated recommendations reflect new research and trends in security, replacing older practices that no longer offer robust protection.
If you’re still enforcing strict rules on password length, frequent resets, and complexity requirements, it’s time to revisit your password policies. The NIST guideline recommendation for passwords presents a more user-friendly approach without compromising security. Let’s dive deep into what the new recommendations entail and why they’re so crucial in today’s cybersecurity landscape.
Key Changes in NIST Password Guidelines
The NIST guideline recommendation for passwords introduces several major changes designed to improve both security and usability. The focus is now on password length, avoiding common practices like complexity requirements, and balancing security with user convenience. Here’s a breakdown of the significant updates:
1. Password Length Over Complexity
The NIST recommends that the emphasis should shift from complex password requirements (e.g., mixing upper-case, lower-case, numbers, and symbols) to encouraging longer passwords. The reasoning behind this shift is that complex passwords are often difficult for users to remember, leading them to reuse passwords across multiple platforms or create easily guessable patterns.
The recommendation encourages a minimum password length of 8 characters and suggests allowing users to create passwords up to 64 characters. This flexibility allows users to opt for passphrases instead of passwords, which are easier to remember and more secure.
2. Eliminating Periodic Password Resets
Older security practices often mandate that users change their passwords every 60 to 90 days. However, this policy led to users creating weak passwords or relying on predictable patterns (such as adding numbers or symbols at the end of a password). The NIST guideline recommendation for passwords advises against forced periodic password resets unless there is evidence of a breach or compromise.
By eliminating unnecessary password changes, organizations can reduce the risk of users creating poor password habits and improve overall security.
3. Avoiding Commonly Used Passwords
The new guidelines recommend that organizations use technology to check passwords against lists of commonly used, compromised, or otherwise weak passwords. Passwords like “123456,” “password,” and even more complex but still commonly reused phrases are highly vulnerable to attacks.
NIST advises using automated tools that screen against these lists to ensure that users are not selecting passwords that are easy to guess or have appeared in previous breaches.

4. Multifactor Authentication (MFA)
The new NIST guideline recommendation for passwords highlights the importance of adding multifactor authentication (MFA). A strong password alone may not be enough to protect against all attacks, so MFA adds a layer of security by requiring users to verify their identity through something they have (e.g., a security token or smartphone) or something they are (e.g., biometrics).
NIST recommends using MFA wherever possible, especially for accessing sensitive systems or data.
5. No Longer Requiring Special Characters
The guidelines no longer stress the need for users to include special characters like “#,” “$,” or “&” in their passwords. Forcing users to combine upper-case letters, symbols, and numbers often results in passwords that are difficult to remember and end up being written down or saved in insecure ways. NIST now recommends that users focus on creating longer passwords, which are inherently more secure and easier to remember, rather than incorporating special characters.
Why These Changes Matter
The NIST guideline recommendation for passwords focuses on modern password security challenges and provides practical solutions to overcome them. Older password policies often created more problems than they solved, pushing users toward insecure habits like reusing passwords or writing them down.
These new recommendations aim to strike a balance between usability and security, offering users more flexibility while also strengthening defenses against password-based attacks. By understanding these new guidelines, organizations, and users can enhance their cybersecurity posture without adding unnecessary friction to their authentication processes.
Best Practices for Implementing NIST Password Guidelines
The NIST guideline recommendation for passwords doesn’t just impact how users create passwords. It also changes how organizations approach user authentication and password management. Here are some practical steps for implementing these new guidelines effectively:
1. Encourage Longer Passwords and Passphrases
Educate users on the benefits of creating longer passwords or passphrases. Instead of mandating short, complex passwords, allow users to craft longer, easier-to-remember passphrases. A 16-character passphrase like “I love hiking on weekends” is far more secure than a short, complex password like “P@ssw0rd!”
2. Check Passwords Against Common Password Lists
Incorporate automated tools that screen user passwords against lists of commonly used or compromised passwords. By doing this, you can prevent users from selecting passwords that are easily guessed or have been exposed to data breaches. Many password managers and security solutions now offer this feature, allowing organizations to integrate it into their security workflows.
3. Implement MFA Across All Sensitive Accounts
Multifactor authentication (MFA) is one of the most effective ways to secure user accounts. Whether through SMS verification codes, authenticator apps, or biometric authentication, MFA adds layer of protection beyond passwords. According to NIST, organizations should make MFA a standard requirement for accessing any sensitive system or personal information.
4. Eliminate Forced Password Expiration Policies
Remove policies that require users to change their passwords at regular intervals, such as every 60 or 90 days. NIST has found that this practice does more harm than good by encouraging users to create predictable passwords. Instead, prompt users to change their passwords only if there is a reason to believe their account has been compromised.
5. Educate Users About Good Password Practices
Make sure users understand the reasoning behind these changes. When people know why long passwords are more secure or why MFA is important, they are more likely to follow best practices. Create training materials, offer resources, and remind users to keep their passwords safe.
The Impact of Poor Password Policies
Poor password policies can lead to catastrophic security breaches, costing organizations millions of dollars and compromising sensitive data. One of the most famous examples is the 2012 LinkedIn breach, where over 117 million user passwords were exposed. The passwords were stored using outdated hashing techniques and many were simple enough to be cracked easily.
More recently, weak passwords have continued to play a role in significant data breaches, demonstrating the importance of implementing strong password guidelines. By following the NIST guideline recommendation for passwords, organizations can significantly reduce their vulnerability to attacks.
Frequently Asked Questions (FAQs)

2. Do I still need to require users to include special characters in their passwords?
No, NIST no longer recommends requiring special characters in passwords. Instead, the emphasis is on creating longer passwords or passphrases that are easier for users to remember and harder for attackers to crack.
3. What’s the minimum password length under the new NIST guidelines?
The new NIST guidelines recommend a minimum password length of 8 characters but suggest allowing users to create passwords up to 64 characters long.
4. Should I eliminate password expiration policies?
Yes, unless you have a reason to believe an account has been compromised, NIST advises against enforcing periodic password changes. This reduces the likelihood of users creating predictable or weak passwords.
5. How can I ensure that users are creating secure passwords?
