Abstract
The present application discloses a password protection method. Aiming at the current problem that, when a plurality of passwords are used, the plurality of passwords may be invalidated after one password is compromised, a password protection method is provided, which comprises: after password authentication is successful, determining, according to a password currently passing the authentication, a specified bit of password invalidation enable identifiers stored in a storage medium, wherein there is only one specified bit because there is only one authenticated password; setting the specified bit to be in an allowed state and other bits to be in a non-allowed state, wherein the password invalidation enable identifiers are in one-to-one correspondence with passwords according to bits, and only when one bit of the password invalidation enable identifiers is in the allowed state, an invalidation operation on the passwords is allowed; determining whether a password invalidation request is received; and if a password invalidation request is received, performing invalidation operation on the password corresponding to the specified bit.
