Two-factor authentication can be enabled on your user profile.
Go to your avatar in the top right corner and select Edit profile.
Slide the two-factor authentication to ‘On’.
The slider will change from grey to teal.
When 2FA is turned on, you'll receive an email with your security code every time you log into Synergy using your user name or email address. The security code needs to be entered before you can access Synergy
The code is required every time you log out of Synergy and try to log back in. If you do not log out of Synergy, you will be asked for the security code on the following day.
