To better protect your email, you will soon need to use Duo two-factor authentication (2FA), in addition to your Dartmouth user name and password to log in to your email on your device (laptop, desktop, tablet or phone). Not all email applications support using Duo authentication, so you may need to use a different application or update your current application to the latest version. For more information go to our Knowledge Base > ITC Event Notices on the Dartmouth Services Portal.
