Duo Bypass Codes

Duo Bypass Codes can be used to access resources protected by Duo when your device is unavailable. You may also need to use Bypass codes if your device is lost, stolen, or replaced. Bypass codes should be placed in a secure location.

Step 2: Generating Duo Bypass Codes

Step-by-step instructions are provided below about how to generate Duo MFA Bypass Codes.

After logging in, you will be asked to choose an authentication method from the Duo Portal.

After choosing an authentication method, you will receive a Duo prompt on your device.

If you installed the Duo Mobile app, click “Send Me A Push.” A Duo prompt will be received on your mobile device. Select “Approve” if you sent the Duo notification to your device. Select “Deny” if you did not send the Duo notification.

If you did not select "Send Me a Push," you can also select “Enter a Passcode,” which can be retrieved in two ways.

The first method to retrieve a passcode involves using the Duo Mobile app, which will generate a 6-digit passcode. Enter that passcode in the blank box and click “Log In.”

The second method used to retrieve a passcode is via SMS text message. Select “Enter a Passcode.” A blue banner will appear on the bottom of the Duo Portal screen. Click “Text Me New Codes.” A code will be sent to your mobile device via SMS text. Input the code in the blank box and click “Log In.”

Once you are able to authenticate, click the “Bypass Codes” tab on the top of the Duo Portal screen. Click Generate to create 10 new Bypass Codes.

Any existing codes will no longer work. You must write down or print the Bypass Codes and store in a safe location. They will only be displayed once and each code can only be used once.

Now, you have have an additional means of authentication in the event you do not have your primary device. Generating these bypass codes will help prevent being locked out of your device!
