Why enroll in two-factor authentication?

Two-Factor Authentication adds an additional layer of security to your Gustavus account. In addition to your password, you will need a mobile device like your phone or a hardware token to verify your identity when logging into your account.

Using just a username and password are no longer considered a secure mechanism for authentication. A password can be stolen or guessed. 2FA protects against password theft or guessing by requiring access to a physical mobile phone or hardware token to successfully login.

A successful information security program is all about adding layers of protection and 2FA is one of those critical layers. Learn more about securing your login by visiting the following page. #LockDownURlogin

How does it work?

1. Access a resource protected by 2FA such as the Gustavus website or GusMail.
2. Enter your username and password as you normally would.
3. Click DUO push to send a verification to your mobile device or it may be automatically pushed to your device. If you do not have a mobile device set up, you can authenticate by entering a previously issued one-time bypass code, or via a hardware token (fob).
4. After verifying it from you, by checking location, you accept a prompt from your mobile device to approve the login. If you have a fob, press the button on the fob, and then type the code that appears on your fob into the web page.
5. Login is now complete.

FAQ

Am I required to enroll in DUO?

Yes, all Gustavus students, faculty, and staff are required to enroll in DUO TFA. This includes anyone who may have retained their Gustavus account after retirement or graduation.

Do I need a smartphone to use Duo?

No, you can have Duo send texts to a regular cellphone, or you can request a list of one-time bypass codes. In certain cases, you may be a good candidate for a hardware token (fob) that you can add your key ring. The fob provides codes that you can enter into the verification menu to access your account. Fobs are easily misplaced and can become unreliable if not used routinely, so this option may not be ideal for everyone.

How can I use my FOB all the time?

The Default Device pop-down does not allow users to choose a FOB as their default device. However, at the Duo Choose an authentication method window, you can select Enter a Passcode. You can then enter a passcode from your fob, the Duo Mobile App on your smart phone, or pre-generated bypass codes.

Does the system allow for multiple hardware tokens and phones to be added to an account?

Yes and we strongly recommend adding multiple options in case one is unavailable. However, GTS only provides one hardware token per eligible user. If an additional one is required, there are several options available for purchase online.

How does it work?

Once you are enrolled, every time you access a web page that uses the Gustavus Single Sign On page, use remote desktop or access the Remote server, you will be prompted with a Duo-Two Factor Authentication option, after you supply your credentials.

If you choose Enter a Passcode, the code can be from the Duo Mobile App on your phone, a fob or generated passcodes.

Do I need to use Duo Two Factor every time I log into my computer?

No, Duo Two Factor is only needed when you are logging into a resource below.

Troubleshooting

When I log into my account on my iPhone, I do not see the Duo screen. I see a blank white/grey screen.

This symptom usually indicates a web content restriction. Please see Duo Mobile's help page for information on how to resolve this issue.

Duo doesn't remember me for 15 days like it says it will on my Internet browsers.

Update your browsers to the newest versions, and then try clearing the website data/cache for duosecurity.com. Also allow cookies for websites you visit.

On my Mac, when I try to update my Internet Accounts for GusMail with my new password, the accounts page freezes and doesn't allow me to update the password.

Open Keychain Access on your Mac, and search for Google saved passwords and remove them. Restart your computer and try again.
