SMB allows for users to access the platform using their Google account, meaning that you don't need to remember your SMB details to access the system.
To set this up, first login to SMB with your normal SMB credentials, then open the "Settings" menu by clicking on your name in the top-right corner of the screen and selecting "My Settings" from the menu.
On the "My Settings" page, scroll down to the "Single Sign-on" panel, which will display whether Single Sign-on is currently enabled. If it is not, click on the "Enable Google Sign On" button to start the process. SMB will then redirect you to Google where you will be asked to provide permission for SMB to recognise your login. No personal or account information is shared between SMB and Google - this simply allows Google to let SMB know that the person accessing the system is authenticated against Google.
Once you have approved the permissions, you will be returned to the "My Settings" page with a confirmation of successful sign-in. From this point, whenever you access SMB, you can use the Google sign-in link at the bottom of the login page to access your account rather than entering your SMB username and password.
You can revoke the Google authentication at any time by returning to the "My Settings" page and clicking on the "Remove Single Sign On" button in the "Single Sign-on" panel.
