You can set the length that User Codes will be when they are generated for users in the SMB app. User codes that have already been assigned to users will not be affected if you change the minimum user code length.
Note that this option only displays if at least one T30 Terminal has been configured for the site. The User Code Length can only be changed before the site has been activated or while in Installer Mode.
To set the minimum User Code length:
If the site has been activated, ask the customer to enable Installer Mode.
Click the User Code Length button.
The User Code Length lightbox displays.
Select the Minimum length from the drop-down list. Generally, longer User Codes are considered more secure.
Click the OK button. New User Codes will now be generated at this length in the SMB app.
