The NIST password guidelines have come a long way, adapting to the forever changing cybersecurity space and, just as importantly, to how people actually behave. When NIST first introduced its password recommendations back in 2017 (under NIST Special Publication 800-63B), the focus was all about security through complexity. You know the drill—passwords filled with uppercase letters, lowercase letters, numbers, and special characters. The idea was that more complexity equals more security.
But soon after, it became clear that all this complexity wasn’t really doing the trick. Instead, it led to users getting creative in all the wrong ways—writing passwords down, reusing them, or making them super predictable (looking at you, “Password123!”). Recognizing this, NIST started to shift its focus in later updates. Rather than pushing complexity, the guidelines began to emphasize password length. Why? Because longer passwords are way harder to crack with brute-force attacks, and they’re usually easier to remember than convoluted combinations.
By 2020, NIST password guidelines took an even bolder step, recommending that people only change their passwords if there was evidence of a breach. This was a huge departure from the old standard of changing passwords every 60-90 days. Turns out, making people change passwords frequently often leads to weaker ones. People would fall back on patterns or slightly tweak old passwords, making them just as vulnerable.
Now, as we look ahead to the NIST password expiration guidelines 2024, the trend is clear—NIST is making security smarter and simpler. The guidelines keep evolving, based on feedback and research, with the goal of balancing strong security with usability.

Key Updates in the 2024 NIST Password Guidelines
The 2024 updates to NIST password guidelines are all about enhancing security while making things easier for users. Here are some of the big changes on the way:
- Password Length Over Complexity
The current NIST password guidelines already emphasize the importance of long passwords, but the 2024 guidelines are taking it up a notch. They’re recommending passwords or passphrases with a minimum length of 12-16 characters. The thinking here is simple: longer passwords are much harder for attackers to crack, and they don’t require you to remember overly complicated combinations. - Elimination of Mandatory Password Expiration
The NIST password expiration guidelines 2024 suggest dropping mandatory expiration unless there’s clear evidence of a breach. In other words, no more changing your password every few months just for the sake of it. This change acknowledges that frequent password changes often lead to weaker choices. Instead, the focus shifts to security events—change your password if something goes wrong, not because a policy says you have to every 90 days. - Support for Diverse Character Sets
NIST is also expanding the range of characters users can choose from when creating passwords. The 2024 update encourages the use of all ASCII characters and even Unicode, which allows for more flexibility and stronger password creation. This means you can get creative with your passwords, pulling in symbols from across various languages and systems, making them even harder to guess. - Prohibition of Password Hints
Another important update is the continued ban on password hints. While hints might sound helpful, they can provide attackers with clues, making it easier for them to crack your password. The 2024 guidelines stick with the advice to avoid password hints altogether. - Encouragement of Password Managers
NIST is strongly encouraging the use of password managers in its 2024 guidelines. If you’re not already using one, it’s time to get on board. Password managers can store and generate strong, unique passwords for every account, and NIST is all about making this practice a norm. Plus, they support the ability to copy and paste passwords directly from the manager, which eliminates the hassle of memorizing everything. - Focus on User Behavior
Understanding how people actually use passwords remains at the heart of the NIST password change guidelines. NIST recognizes that people often fall into predictable patterns when creating passwords. By addressing these behaviors head-on, the 2024 guidelines aim to foster better security habits while reducing the burden on users.
Evolution of NIST Password Guidelines
| Feature | Current NIST Guidelines | 2024 NIST Guidelines |
| Password Length Requirement | Minimum 8 characters | Minimum 12-16 characters |
| Complexity Requirements | Required (mix of cases/special characters) | Not required; focus on length |
| Password Expiration | Every 60-90 days | Only on known compromise |
| Use of Password Hints | Allowed | Prohibited |
| Support for Character Sets | Limited | All ASCII & Unicode supported |
| Encouragement for Password Managers | Limited | Strongly encouraged |
Benefits of Implementing the 2024 NIST Password Guidelines
So, what’s in it for you and your organization if you follow the 2024 NIST password guidelines? Turns out, quite a bit. Here’s a breakdown of the benefits:
- Better Security Without the Hassle
By focusing on password length instead of complex combinations, you’re getting stronger security without making things harder for users. Long passwords are much more resistant to brute-force attacks, and because users don’t need to remember convoluted character strings, they’re less likely to resort to risky habits like reusing passwords across multiple accounts. - Fewer Password Changes
The NIST password change guidelines reduce the need for frequent password updates. This is a win for everyone—users aren’t forced to come up with new passwords every few months, and IT departments will see fewer help desk calls related to password resets. Plus, fewer changes mean people are less likely to use weak passwords or fall back on slightly modified versions of old ones. - Stronger Passwords, More User-Friendly
Thanks to expanded support for diverse character sets, users can get creative with their passwords, making them harder to guess and increasing security. Allowing the use of all ASCII and Unicode characters opens up endless possibilities for unique and secure passwords that are still easy for the user to remember. - Better Compliance with Regulatory Standards
Many organizations need to follow strict regulatory frameworks, and aligning with NIST 800-63 password guidelines helps meet those requirements. Whether you’re in healthcare, finance, or any other industry dealing with sensitive information, following NIST’s guidelines can boost your overall compliance and security posture. - Reduced Risk of Attacks
By encouraging the use of password managers and focusing on behavior, the 2024 guidelines help reduce the risk of common password-related vulnerabilities. Weak passwords and reused passwords are often the easiest entry points for attackers. Implementing current NIST password guidelines (and the upcoming 2024 updates) greatly lowers this risk. - Cost Savings Through Fewer Password Resets
Every time a user has to reset a password, it costs time and resources. Implementing the 2024 NIST password expiration guidelines—which reduces unnecessary password resets—will likely result in cost savings for your organization. Less time spent dealing with password issues means more time spent on productive work.
The 5 Functions of NIST
NIST’s password guidelines are just one part of a broader framework aimed at improving security practices across the board. The 5 functions of NIST—Identify, Protect, Detect, Respond, and Recover—help organizations build a comprehensive cybersecurity strategy. Password management falls primarily under the “Protect” function, but it’s also tied to “Identify” by verifying users and ensuring they’re who they claim to be. Following the NIST password guidelines plays a key role in building a solid foundation for cybersecurity.
