Detailed explanation-1: -Passwords should not expire. Users should be prevented from using sequential characters (e.g., “1234”) or repeated characters (e.g., “aaaa”).
Detailed explanation-2: -To protect enterprise assets and users, many security best practices advise periodic password changes. However, this age-old “conventional wisdom” is not recommended by the National Institute of Standards and Technology (NIST). Here’s why.
Detailed explanation-3: -According to the NIST Special Publication 800-63B, password length has been found to be a primary factor in characterizing password strength. NIST password length requirements are that all user-created passwords be at least 8 characters in length and all machine-generated passwords are at least 6 characters in length.
Detailed explanation-4: -The NIST recommends resetting passwords only when necessary. Generally, organizations have a password expiration policy that allows passwords to be 60 to 90 days old at max. The NIST doesn’t recommend password expiration due to the above mentioned reason.
Detailed explanation-5: -A minimum of eight characters and a maximum length of at least 64 characters. The ability to use all special characters but no special requirements to use them. Restrict sequential and repetitive characters (e.g. 12345 or aaaaaa). More items •26-Feb-2020
