In password security, the longer the better. With a password manager, using more than 24 characters is simple. Unless, of course, the secure password is not accepted due to its length. (In this case, through STOVE.)
Possibly indicating cleartext storage of a limited field (which is an absolute no-go), or suboptimal or lacking security practices.
Exactly. The tax on hashing the password can’t be ignored and if you’re doing this enough times it can kill a system. 24 characters is too low. I’d say 100 characters is enough for most use cases. 1024 if you’re feeling 1337.
Sure, but when we talk about the computation then the number of rounds is by far the more important factor compared to password length.
The discussion is about whether 24 characters indicate cleartext though - not whether password lengths should be in the gigabytes.
