Password generators fail users’ length and site-rule constraints

Password-manager users want generated passwords and passphrases that fit website limits and their own preferences, but generator settings can restrict length or word count. When a site rejects a password, its rules may be unclear, leaving users to relax settings incrementally or switch to an online generator. A separate, adjacent need is generating likely combinations when recovering an encrypted file.

For password-manager users. Mentioned from Oct 2024 to Oct 2025 on product forums, Hacker News and Stack Exchange.

  1. The built in passphrase generator was one of my favorite features up until a few days ago when I noticed I wasn’t ALLOWED to make a password that would fit into a website’s max length
  2. At the moment I have simply stopped using Bitwarden’s password generator feature and am using an online generator
