'The National Institute of Standards and Technology (NIST), the federal body that sets technology standards for governmental agencies, standards organizations, and private companies, has proposed barring some of the most vexing and nonsensical password requirements. Chief among them: mandatory resets, required or restricted use of certain characters, and the use of security questions. Choosing strong passwords and storing them safely is one of the most challenging parts of a good cybersecurity regimen. More challenging still is complying with password rules imposed by employers, federal agencies, and providers of online services. Frequently, the rules—ostensibly to enhance security hygiene—actually undermine it. And yet, the nameless rulemakers impose the requirements anyway. [...] 1. Verifiers and CSPs SHALL require passwords to be a minimum of eight characters in length and SHOULD require passwords to be a minimum of 15 characters in length. 2. Verifiers and CSPs SHOULD permit a maximum password length of at least 64 characters. 3. Verifiers and CSPs SHOULD accept all printing ASCII [RFC20] characters and the space character in passwords. 4. Verifiers and CSPs SHOULD accept Unicode [ISO/ISC 10646] characters in passwords. Each Unicode code point SHALL be counted as a single character when evaluating password length. 5. Verifiers and CSPs SHALL NOT impose other composition rules (e.g., requiring mixtures of different character types) for passwords. 6. Verifiers and CSPs SHALL NOT require users to change passwords periodically. However, verifiers SHALL force a change if there is evidence of compromise of the authenticator. 7. Verifiers and CSPs SHALL NOT permit the subscriber to store a hint that is accessible to an unauthenticated claimant. 8. Verifiers and CSPs SHALL NOT prompt subscribers to use knowledge-based authentication (KBA) (e.g., “What was the name of your first pet?”) or security questions when choosing passwords. 9. Verifiers SHALL verify the entire submitted password (i.e., not truncate it).' -- source: https://arstechnica.com/security/2024/09/nist-proposes-barring-some-of-the-m... Cheers, Peter
