Hi @Drees ,
the mandatory MFA requirement affect free or Pay-As-You-Go accounts.
Please take a look here: Scope of enforcement
There is no Microsoft Entra ID P1 or P2 license required:
- If you don't have a Microsoft Entra ID P1 or P2 license, you can enable security defaults. Users are prompted for MFA as needed, but you can't define your own rules to control the behavior.
