You can disable authentication with a username and password as described below.
Note
This feature affects only the logins using the Authentication server, such as logging into Teamwork Cloud from web applications and from a modeling tool using SSO.
To disable authentication with a username and password
Go to the Teamwork_Cloud_installation_directory\WebAppPlatform\shared\conf directory and open the authserver.properties file.
In the file, find the authentication.disable.credentials property and change its value to true.
