Duo Two-Factor Authentication
Brandeis has enabled two-factor authentication using the Duo service. Two-factor authentication serves as an extra layer of security designed to prevent unauthorized access to your account and personal information. Duo protects your Brandeis account by requiring two forms of authentication to verify your identity when logging into Brandeis services:
- Something you know: your Brandeis username and password
- Something you have: a physical device (such as mobile phone, tablet, or landline phone

Once you are in the Duo Authentication page, click the check box at the bottom that reads Remember me for 30 days. After you have fully authenticated, your browser will not require you to do this again when you come back at a later session (within the 30 day period).
Note: Two-step authentication is requested at least every 30 days for each computer and each browser you use to access Brandeis protected websites.
If you are unable to select the 'Remember me for 30 days' checkbox and are prompted with a "You need to enable cookies in order to remember this device" message, you likely have the cookie settings pictured below*.

If you are traveling and you have limited or no cellular service or internet connection, please review the following options:
- Obtain a hardware token from the Technology Help Desk before traveling.
- Have Duo send a list of 10 passcodes to your phone before you leave. On the Duo Authentication screen, select 'Enter a Passcode' then click 'Text me new codes'.

A hardware token is a two-step authentication device that generates and displays a six-digit passcode at the push of a button. The device does not need wireless access or a data connection. Tokens are available upon request.
Contact the Technology Help Desk to request a hardware token. It will need to be activated by a Technology Help Desk staff member before leaving the Help Desk area.
Contact the Technology Help Desk ASAP. We will replace it for you, and can assist with deactivating the lost one.
Please call or come to the Technology Help Desk as the token will need to be reset by a staff member.
Contact the Technology Help Desk to deactivate your old phone number/device and register a new one for Duo.
Duo is not currently compatible with Google Authenticator or LastPass Authenticator.
If you have Google 2-Step enabled on your Brandeis account, Duo is intended as a replacement. You may use both; you will be prompted twice for a second authentication factor (by Duo and Google).
If you use the Duo mobile app, you can still register your smartphone as your second factor. The Duo mobile app will create a Brandeis profile alongside your existing profile. If you currently use a hardware token, you will need to obtain a second hardware token from the Technology Help Desk.
