Two-Factor Authentication with Duo

Two-factor authentication, also referred to as 2FA, protects users from unauthorized access to Lehigh accounts in the event that a password is compromised. 2FA is currently only licensed and required for faculty and staff. You may already be familiar with 2FA if you've accessed sites that require it, such as for online banking. Two-factor authentication uses two pieces of information to establish your identity when you are trying to access a site or service:

• The first factor is something only you know, such as your password.
• The second factor is something only you have, such as your mobile phone (recommended).

If your password is compromised through a phishing attack or other malicious means, a cyber criminal would also need your second factor to access your account.

Lehigh has contracted services from Duo Security to enable two-factor authentication on your Lehigh computing account. Duo's services allow you to choose the type of authentication method that works best for you: a push notification sent to your mobile device through the Duo Security app, a generated code each time you log in to a site or service, or another device such as a telephone to call you when two-factor authentication is needed.
