This is a rant about dumb password policies enforced by some websites or apps. If you see these password rules forced to you, try to stay away if possible.

Can’t use special characters, or use a pre-defined special characters only

Are you storing the password in plaintext that your database will break when have special characters?

Password can’t be longer than X characters

Most probably storing the password in plaintext and their database column is limited to those characters limit.

Password expire every X months, without notice, suddenly can’t login. Reset it and can’t use the last 5 passwords

They store your previous passwords, either encrypted or plaintext.

    Some password hashing functions have a maximum input length. That could be a reason for some of the requirements. E.g. if I remember correctly, bcrypt used a maximum of 60 characters, while still being an ok choice for a hashing function
