Methods and apparatus for logging into a computer. The computer receives a username and password. The computer determines whether a user with the username is authorized to access the computer. If so, the computer retrieves a weak cryptographic hash of the user's password and compares it to a weak cryptographic hash of the received password. The computer grants access if the weak cryptographic hashes are identical, and sends the username and password to a server. The server determines whether a user with the username has a server account. If so, the server retrieves a strong cryptographic hash of the user's password and compares it to a strong cryptographic hash of the received password. The server grants the user access to an account or service if the strong cryptographic hashes are identical.
