Passcodes for user authentication

Web Authentication supports the use of passcodes to authenticate users. Users are blocked from accessing the switch until they enter a valid passcode on a web login page. Unlike username and password authentication, passcode authentication uses a simple number to authenticate users. The simplicity of a passcode reduces user errors and lowers the overhead of supporting and managing simple tasks, such as Internet access for guests and visitors in the office.

When passcodes are enabled, the system automatically generates them every 1440 minutes (24 hours), and when the system boots up. You can optionally create up to four static passcodes that will be used in conjunction with the dynamic passcodes generated by the system.
