Enforce FIDO2 PIN complexity with Microsoft Entra Conditional Access Authentication Strengths.

As you may or may not know, most FIDO2 security keys can be set up with easy PINs like 1111 or 123456. Just like passwords, users tend to come up with easy-to-remember PINs. Token2 recently announced their PIN+ series, a line of FIDO2 Security keys. These security keys feature advanced PIN complexity rules that set a new standard for security. PIN+ keys implement specific complexity rules for both numeric and alphanumeric PINs, which can be found here. With the use…

Company branding and custom CSS in Azure Active Directory

Company branding in Azure AD is a nice feature that allows administrators to prettify the sign-in experience for their end-users. It also comes with the possibility of ingesting custom CSS code. A client recently moved from ADFS to Azure AD, and they wanted to update the sign-in screen to look more like the good old ADFS theme. Now, this is pretty easy to do, but by default, the background image comes with an overlay to improve contrast and legibility. Time…

Step-up authentication with Defender for Cloud Apps and Authentication Context

Send an email on a new Azure MFA method registration

I’ve done quite some Azure MFA projects over time (and counting), and as we mainly focus on the technical side, there are also practical sides to consider. Every project has its own approach and challenges, and more importantly: the user is impacted more or less, and that asks for some guidance. Now, this solution comes in handy if you want to act on new registrations for Azure MFA methods. That can be an action of any kind. To give you…

Report Suspicious Activity & Fraud Alert for Azure MFA

A new feature popped up in Azure AD. Well, not entirely new, I must say. Reading from the docs, Report Suspicious Activity is an enhancement of the Fraud Alert feature that has existed for quite some time. Until now, administrators could enable Fraud Alert for Azure MFA so that users could report when suspicious MFA prompts are received. Users who reported fraud could be automatically blocked so they could no longer sign in. As this is a good feature, it…

System-preferred multifactor authentication in Azure AD. Don’t settle for less.

A new feature has popped up in Azure AD: System-preferred multifactor authentication (MFA). This will allow administrators to enforce the most secure method for Azure MFA. For example, if a user has multiple methods registered, the most secure method will be prompted first. How do I know what method is the strongest, you may ask? Here is the current order from most to least secure methods, currently supported in Azure Active Directory: This list is dynamic and may change as…
