Sign-in Frequency - How It Works and When to Use It
Sign-in Frequency (SIF) is a commonly misunderstood control, one many orgs use to inflict unnecessary suffering on their employees 😩 It probably doesn’t work the way you think it does and is often used in less than ideal ways… So let’s look at how it works and when to use it. Original documentation excerpt introducing sign-in frequency and the risks of repeatedly asking users for credentials. Historical November 2025 documentation screenshot. Its broad session-revocation wording must not be treated as a guarantee for every application; use current, qualified guidance.

👮 Restricted Management Admin Units (RMAU) in #EntraID Hackers HATE This Hidden Entra ID Feature Most Admins Never Use@NathanMcNulty breaks it down for us 👇 🎧 Get the full podcast episode at https://t.co/gnvH23WorW pic.twitter.com/nxBwCQ6BwS — Merill Fernando (@merill) March 29, 2025 I recently had a chance to discuss Restricted Management Administrative Units (RMAUs) with Merill, and one of my favorite uses for these is to protect groups that are used in Conditional Access policies so they aren’t accidentally modified or deleted. I’m also a big fan of using Access Packages to control membership of these groups for things like exclusions from geofencing policies, user action policies, blocking policies, etc.
