Generate Duo Bypass Codes in Advance

If you don't use the Duo Mobile app, be prepared with Duo: Generate and Use a Bypass Code

You can use bypass codes whenever you need to sign in where you have no WiFi or cell service. The codes are good for one year (365 days), so even if you are planning on spending a lot of time "off the grid," you will be able to access online systems, data, and assets.

Dead Phone

If you have not enrolled a backup device and/or have not generated Duo: Generate and Use a Bypass Code, you'll need to get a temporary security code by visiting a walk-in location with a valid ID.
