Intune - Phishing-Resistant MFA
Good Afternoon, So sorry but I'm quite novice. I am trying to merge all Intune users to phishing-resistant MFA (PR-MFA) only (excluding break-the-glass users/admins). On Entra, I do this by disabling Microsoft-Managed MFA and setting a new authentication strength with all three (PR-MFA) modalities selected as the only allowable MFA. Then, I set a conditional access policy to grant all users to access all resources only if they have PR-MFA registered, because I don't want them to use other MFA like SMS. This makes all existing users switch over and disables weaker methods (like text messages), but I can't onboard new users. I reviewed the log for a test user who I could not register, and I saw that the issue is that during registration, the passkey must already exist BEFORE the new user can set up a passkey or other PR-MFA method, which is impossible. Is there a way to let Intune use just the new user's password alone for initial PR-MFA registration?Solved439Views0likes2Comments
