Use the guest user account to authenticate users (such as partners and contractors) who do not have the necessary logon credentials. Guest users can also be subject to TMWS policies.
Note:
The guest user account works only for user clients accessing through the Virtual Gateway or on-premises gateway with Guest User Logon enabled.
Change the account name (optional) and set the password for the predefined guest user account. It is not possible to configure additional guest user accounts.
