'Is it possible to enable MFA for the guest users?
I have created guest users in my Azure AD tenant by sending invitations via email following this link https://docs.microsoft.com/en-us/azure/active-directory/external-identities/b2b-quickstart-add-guest-users-portal.
The guest users are added to my tenant once they accept the invitation. Now I have assigned some applications to the guest users that they can access.
To enhance the security, I want to enable two-factor authentication for the guest users when they are accessing the application. Is it possible to enable MFA for the guest users? If yes, can anyone guide me with the steps
