User authentication may sound very secure but it is not so secure. You need just the username and PASSWORD to break into or HACK into the authentication of that person. The main way of hardening is by choosing the password accordingly. You can either generate memorable PASSWORDS which are secure, passwords based on ALGORITHM, making the USE of password vaults, using authentications which are multifactor and highly secure and alternate embedding of the alphabets of a specific memorable word, are the best ways of hardening user authentication.
