Abstract
Embodiments herein provide, for example, a method that includes downloading a symmetrically encrypted data block from a server, where the encrypted data block comprises a server-stored secondary password; decrypting the encrypted data block with a shared-symmetric key; signing onto at least one of a server or service using the server-stored secondary password; generating a secondary password, where the generated secondary password is different than the server-stored secondary password; and overwriting the server-stored secondary password with the generated secondary password.
