Time-based one-time password (TOTP) authentication
When users log on to a Domino Web server, you can require that they provide time-based one-time passwords in addition to their user names and passwords.
Time-based one-time password (TOTP) authentication provides an extra layer of security when users authenticate to a Domino Web server. When TOTP is enabled, users are required to provide a time-based one-time password (token) in addition to their names and passwords. Session time-out that is configured on the Domino server controls how often users are prompted to log in and provide both credentials.
