Password-authenticated key retrieval is a process in which a client obtains a static key in a password-based negotiation with a server that knows data associated with the password, such as the Ford and Kaliski methods. In the most stringent setting, one party uses only a password in conjunction with "N" (two or more) servers to retrieve a static key. This is completed in a way that protects the password (and key) even if "N" − 1 of the servers are completely compromised.
