Hi James Allen ,
Welcome to the Microsoft Q&A Platform! Thank you for asking your question here.
We understand from your query that you are experiencing an issue while trying to log in to Azure AVD with MFA enabled, and you are unable to log in.
Please work on below steps:
- Conditional Access policy issue: If you have Conditional Access policies configured, review them to ensure they're not blocking the user's login attempt, and please ensure have you followed these steps while configuring MFA https://learn.microsoft.com/en-us/azure/virtual-desktop/set-up-mfa?source=recommendations&tabs=avd#create-a-conditional-access-policy
- MFA configuration issue: Double-check the MFA configuration for the user and the Azure Virtual Desktop (AVD) environment. Ensure that the MFA method is correctly set up and that the user has been enrolled in MFA.
- MFA token or code issue: If the user is using a time-based one-time password (TOTP) or a smart card for MFA, ensure that the token or code is correct and up to date.
- Test from different devices and clients to see if the issue persists. Sometimes client-specific issues can impact MFA.
