Within Teamwork, you can enable the Google Sign In integration to allow users to sign in to your site using their Google account.
Click your profile icon in the top right corner of your site and select Settings from the dropdown menu.
In the settings area, go to the Integrations tab where you will see a section for Google Sign In. Click Connect to get started.
Once it has been enabled, you will see an option to manage the domains for the integration.
Providing your domains means you will be given an extra option of creating new user accounts automatically.
Once the Google Sign In integration has been enabled, users will see an extra option on the log in launchpad to sign in with Google.
