A computer-implemented method is disclosed. The method includes: receiving, via a computing device in a locked state, input of a first PIN; determining that the first PIN is associated with a first cryptographic key that is stored in a memory; responsive to determining that the first PIN is associated with the first cryptographic key, retrieving, from the memory, an encrypted form of a first credential that is associated with the first cryptographic key; recovering the first credential from the encrypted form using the first cryptographic key; and causing the computing device to be unlocked using the recovered first credential.
