Abstract
An approach is provided that uses multiple hashing algorithms to verify a password. The approach receives a password that corresponds to a user identifier. A set of hashing algorithms are retrieved with the retrieved set based on the received user identifier so that different user identifiers utilize different sets of hashing algorithms. Hashing the password using each of the hashing algorithms included in the set of algorithms with the hashing resulting in a hash result. An expected hash result that corresponds to the user identifier is retrieved and the approach then verifies the received password by comparing the hash result to the first expected hash result.
