# CompareHashedPassword(Password, String, Byte[], IPasswordAlgorithm, Object[]) Method
Compares an unencrypted *password* with a stored, encrypted *existingPassword*. This method uses the specified *algorithm* to retrieve the hashed version of the *password* and then compares it with the *existingPassword*.
