$begingroup$ I understand that password storage frequently utilizes hashing for stability as a result of it being irreversible and that the saved hash is simply in comparison to the hash with the password inputed by a user attempting to log in. As hashes are mounted size, does that necessarily mean that even if not specified when creating the password, all login systems would want to have some type of highest input length (Despite the fact that most likely quite high)?
