active directory multi factor authentication

If a user is blocked, you can unlock them in the Block/unblock users. Here you can enable Fraud Alerts, and configure if users will automatically be blocked from signing in if they submit an alert. Go to the Azure Portal and launch Azure Active Directory > Security > Multi-Factor Authentication > Fraud Alert. The problem with this is that leaves a 1 in 4 chance an accidental selection may result in unauthorized access.įraud Alerts allow your users to report fraud if they receive a two-step verification request that they didn’t initiate and automatically block their account from sign-on. Some improvements to this have been multiple number options where the end user must select one of four numbers that is presented on the screen they are logging into. Traditionally, MFA notifications are push notifications where a user can either accept or deny the request. Microsoft has several items to help prevent MFA fatigue attacks that you can configure and enable for your end users. The attacker continuously sent MFA requests to an end user hoping they would accidentally approve one of them. Recently, Uber appeared to be hacked in what is called a MFA Fatigue attack. Show geographic location in push and passwordless notifications.Show application name in push and passwordless notifications.Require number matching for push notifications.The only setting which shows any effect is the property 'Multifactor authentication -> MFA enforcement' in the User Flow. However, no matter what we configure in this Conditional Access Policy, it just doesn't make any difference. We created a Conditional Access Policy and selected only certain users (for which we would like MFA to be active). So recently we figured that it's possible to enable MFA conditionally by enforcing a Conditional Access Policy. But this is a route we would like to avoid at any cost. The only way to achieve this was to use Custom Policies. This feature used to be only available for Azure Active Directory but not for Azure Active Directory B2C.

So every user can choose if he/she is prompted for MFA or not.

We want to achieve Multi-Factor-Authentication on a per-user-basis using Azure Active Directory B2C.
