Summary:In an approach for authentication of a username, a processor maintains a mapping of usernames and realms. A processor receives a username and a time-based one-time password code (TOTP code) for the username based on an authentication application. A processor, upon receiving the TOTP code: determines a realm from the mapping based on the received username and the received TOTP; and requests an entry of a credential relating to the username in the realm. A processor, upon receiving of the requested credential, authenticates the username by determining that the received credential matches an expected credential for the realm.
