Self-Service Password Reset with SMS in Microsoft Entra External ID — Because Apparently People Still Forget Passwords

Oh great, another bloody article about users forgetting their goddamn passwords. Because apparently typing eight characters twice a year is too much to ask. The geniuses at Microsoft have now blessed us with a self-service password reset (SSPR) feature in Entra External ID using SMS — you know, because sending sensitive reset codes over text messages totally screams “secure, enterprise-grade solution.”

So here’s the gist, straight from the trenches: you set up this shiny new SSPR system for B2C or B2B external users, giving the freeloaders a chance to fix their own password screw-ups…with their phones. Basically, it means you can link an SMS-based verification method so that when external morons—uh, I mean users—inevitably forget their passwords, they can beg a robot to text them a code. They punch that in, set a new password, and voila, less ticket spam for your helpdesk. Halle-bloody-lujah.

Of course, in true Microsoft fashion, it’s not just “click and done.” Oh no, you’ve got to configure Entra External ID, set up proper policies, tweak authentication methods, and make sure the right permissions are in place so you don’t accidentally grant the intern full admin rights to your tenant. Then, after jumping through these flaming hoops of joy, you get the holy grail of fewer password reset requests — at least until someone loses their phone and blames IT for it.

The article walks you through all the boring steps — creating a new user flow in Entra ID, configuring SMS providers, customizing responses, and testing things so Karen from Accounting can stop calling because “the system won’t let her in.” It’s all pretty standard Microsoft ceremony, wrapped in more menus than a goddamn 90s video game.

So yeah, it’s a decent feature if you want your end users to stop pestering you every Monday morning because they “forgot” their password again. Just don’t expect it to make them any smarter, or for your infrastructure to magically not break during rollout. Microsoft giveth, and Microsoft taketh your sanity away.

Reminds me of the time a user called because their keyboard “stopped typing passwords.” Turns out Caps Lock was on. I told them I’d “remotely fix it” and just muted the phone until they hung up. Good times.
