passcodes
Digital entry keys
Passcodes are sequences of characters—usually numbers—used to verify identity or grant access.
The term emphasizes codes you must remember and enter, as with phone unlock screens or security systems: Enter your four-digit passcode.
Passcode and password overlap in meaning, though passcode often implies a shorter numeric sequence.
