Associating biometric information with passwords is disclosed. If biometric information received from a user matches stored biometric information, stored passwords associated therewith are retrieved. If these stored passwords are identical to access-enabling passwords, then the user is permitted to gain access associated with the access-enabling passwords. If the biometric information matches the stored biometric information but the stored passwords do not match the access-enabling passwords or are not present, then the user is requested to manually enter passwords, which are stored. If these stored passwords are identical to the access-enabling passwords, the user is permitted to gain access. However, if the biometric information does not match the stored biometric information, or if the biometric information has not been received from the user or is not present, then the user is requested to manually enter passwords. If these passwords match the access-enabling passwords, then the user is permitted to gain access.
