Multi-factor authentication can sometimes stop working, for example when you change your phone. In this case, multi-factor authentication needs to be reset and re-enabled.

1. You can reset multi-factor authentication yourself using your bank credentials in OMA as follows: Go to https://account.jyu.fi and click on "Reset multi-factor authentication" at the bottom left of the login window.
   
2. Click on the "Continue to authentication" button. Make sure you have your bank details nearby.
   
3. Choose the authentication service you use, e.g. your mobile account or your bank, and authenticate with the service you choose. After authentication, you will be redirected back to the OMA service.
   
4. On the reset page, select which multi-factor authentication service (Microsoft MFA or Duo MFA) you want to reset and click the Reset button.
   
5. After the reset, the service will click the Continue button. The example shows a reset of the Duo mobile MFA.
   
6. After the reset, do the deployment again:
   • Setting up Duo mobile multifactor authentication
   • Setting up Microsoft multifactor authentication
