I forgot to bring my mobile device or token to work. What do I need to do?

If you have an alternate authentication method (such as your desk landline or hardware token), please use that, otherwise, please contact the OIT Help Desk for a temporary bypass code.

If my hardware token is lost or stolen, what do I need to do?

Please contact the OIT Help Desk to initiate a request for a replacement and request a bypass code if needed.  If you have an alternate device setup for two-step, please use that device to remove the hardware token from your account.

Can I use two-step login without internet/cell service?

The Duo mobile app can generate passcodes on Android and iOS without needing access to the internet, they can be entered on the two-step prompt as indicated below.  The hardware token will also function without issue.

Can I use two-step when traveling internationally?

You can use two-step while traveling abroad. All authentication methods are available internationally, though some require internet or cell service. When cellular service or internet access is not available, the mobile push, call, and SMS options will not be available to your device. In this case, you can still use the Duo mobile passcodes as indicated above, or hardware token if you have one. You can also request 10 one-time-use passcodes to be sent by text message before you travel.

What are some of the common support issues?

Automatic push issues

If you have two-step set to send a push notification to your device automatically and you are trying to use another authentication method or you are trying to add a new device, you must first click cancel in the bottom right corner before proceeding.

Remember-me issues

If you have automatic push setup, you will first need to cancel the automatic push, then press the remember me for 30 days option at the bottom left of the two-step prompt.  Please see the picture above on how to cancel an automatic Duo push.  Once canceled you may check the checkbox for “Remember me for 30 days” and then complete your authentication (i.e. sending another push to your device).

The Remember Me feature relies on cookies and when enabled correctly, you will not be asked to complete two-factor authentication the next time you are on the same browser. Please be aware of the following restrictions that can impact Remember Me feature and adjust your settings as necessary:

Chrome incognito does not provide support for Remember Me as cookies are cleared at the end of the session.

Internet Explorer has a “Delete browsing history on exit” in its General setting. If this is enabled, the Remember Me feature will not work.

Some browsers may have restricted security settings to only allow cookies from authorized sites. If so, please add add “” as a trusted site.
