Azure app to always ask for MFA

[RahamimL]

Hi all,

We have an Azure APP that we want to always ask for MFA code. This is a sensitive app that requires connecting from outside our LAN.

Right now, our service settings is set to allow users to remember MFA on devices they trust for 30 days.

I need to bypass this and force the users to always enter credentials every time they login to the app.

Is there a way to do that?

Thanks, Rahamim.

Afaik you cannot. @Daniel Stefaniak was just discussing a similar scenario on another board, perhaps he can tune in here as well.

in genera prompts are bad for security:

This isn't about breaking SSO, I need a way to give the user a prompt for credentials because the azure app is sensitive and my users don't always come from a trusted computer.
Think about it like always using Skype for business plug-in when adding to the URL "?sl=1".
Thanks, Rahamim.

@RahamimL you can set MFA policies per app if you have Azure AD P1/P2 using conditional access. However, AFAIK it can not be used to overrule the "remember MFA for 30 days".
