Duo Authentication Loop in Safari

If you are using the Safari Browser (or it will sometimes happen in Chrome, as well) & Duo seems to loop from the Duo authentication screen into the app/service & then right back to the Duo prompt, please try one of the solutions below.

  • Close the Safari Browser & then open it to try Duo authentication again (you can try just closing any unnecessary open tabs at first, if it is not convienient to close the entire browser).
  • Restart the iOS device & try Duo authentication again

The process of restarting the device or the browser allows for memory reallocation back to the system & will temporarily resolve the issue with Duo getting stuck in a loop. However, the issue can reoccur in the future & the fix would be the same.
