Using Duo with external mail applications

If you use an external mail application on your computer, such as Thunderbird, Outlook, Apple Mail, you will be prompted for Duo when you setup the account and the next time you use the app after you change your domain password.  

If you already have your Wellesley account setup in a mail app, you will not be prompted to login again until you change your domain password.  When you change your domain password, you may need to remove your account and add it again to get the Duo authentication prompt.  If you need help with this, contact the Computing Help Desk.

  2. If you aren't prompted to add an account, in the menu bar, go to Mail > Accounts...

  5. In the Wellesley login screen that appears, enter your username and password and click Login.
  6. You should then get a Duo prompt.  Authenticate through Duo. You do not need to check the Remember me for 30 days because the mail app will remember your account information.
