Configuring the Length of Dynamically Generated Passcodes

By default, dynamically generated passcodes are 4 digits in length; for example, 0123. If desired, you can increase the passcode length to up to 16 digits. To do so, enter a command such as the following at the Web Authentication level of the CLI.

device(config-vlan-10-webauth)# auth-mode passcode length 10

The next dynamically created passcode will be 10 digits in length; for example, 0123456789.

The passcode can be a number from 4 to 16 digits in length.
