Typically, the advice is "use a more modern system like argon2id". However, I did notice some sites mention that systems ought to check for a maximum length of 72 bytes when using bcrypt: https://cheatsheetseries.owasp.org/cheatsheets/Password_Storage_Cheat_Sheet.html#input-limits As far as I can tell, PHP does not do this check. I am not sure if the implementation(s) used suffer(s) from the limitation that is the source of this recommendation. Perhaps someone has time to investigate this? Anyway, it's "future work." I have voted for 11, but will not be hurt in any way if 12 wins.
