Faculty, Staff, and PhD Students

Contact your IT Support Representative for the best option to use with two-step verification.


Two-Step Methods: Key

Push Notifications - The best balance between security & convenience, just approve the push notification to sign-in!

Authenticator App - Use virtually any app available -- this method generates a code every 30 seconds that you'll need to manually enter. 

Physical Security Key - No need for a phone, just keep the FOB on your keychain for easy two-step verification on the go!

Voice or Text Message - The least secure form of two-step verification, receive a code via text or voice message. Make sure you have cell reception!
