Entra ID Is Finally Dragging Authentication Out of the Stone Age, Kicking and Screaming

Microsoft has decided that in 2026, passkeys will become the default authentication method in Entra ID, which is just a polite corporate way of saying they’re finally trying to stop people from securing their accounts with the digital equivalent of a wet cardboard box.

The big news is this: SMS and voice-based MFA are being shoved toward retirement, and honestly, about bloody time. Those methods have been hanging around like some knackered old server in a broom cupboard, still technically working but mostly just causing grief, security holes, and endless support tickets. SIM swapping, phishing, interception—yeah, all that fun shit. Turns out sending codes over text messages wasn’t the pinnacle of security engineering after all. Who could have fucking guessed?

Passkeys, on the other hand, are being pushed as the shiny new default because they’re more resistant to phishing, easier for users, and don’t rely on people typing in six-digit codes they’ve already forgotten by the time they switch apps. They’re based on public-key cryptography, which sounds fancy because it is, but the important bit is that it’s a hell of a lot harder for some random bastard on the internet to steal and reuse compared to passwords and SMS codes.

Microsoft is also continuing its long, slow campaign to murder passwords, which frankly should have happened years ago if people weren’t so stubborn and vendors weren’t so addicted to legacy crap. The article explains that Entra ID will guide users toward the strongest authentication methods available, meaning passkeys get top billing while weaker methods get pushed into the corner where they belong.

There’s also a management angle here for admins, because of course there is. Organizations will need to plan for the transition, clean up authentication policies, and prepare users for the change before the usual herd of confused muppets starts clicking whatever shiny button they see first. If your environment still leans heavily on SMS or voice, congratulations: you’ve got work to do. Dust off your rollout plans, update your documentation, and prepare for the whining.

The broader point is that Microsoft wants sign-ins to be more secure and less idiotic. Passkeys are supposed to make authentication faster, simpler, and less vulnerable to phishing. Meanwhile, SMS and voice are being nudged toward the grave because they’re weaker, more exploitable, and generally a pain in the arse. So yes, the future of Entra ID authentication is passkeys, and the old methods are being taken out behind the shed.

In summary: Microsoft is making passkeys the default in 2026, pushing users and admins toward stronger, phishing-resistant authentication, and quietly putting SMS and voice MFA out to pasture where that obsolete shit belongs. If you haven’t started preparing, now would be a fantastic time to stop faffing about and get on with it.

Anecdote time: years ago, some genius insisted SMS MFA was “good enough” right up until his phone number got hijacked and his account was used to spray nonsense across half the tenant. Then suddenly he wanted “that modern secure stuff” immediately, as if I kept a magic wand under the desk next to the cattle prod. Funny how security becomes urgent only after everything goes tits up.
