I took this to mean that you have to use the Microsoft Authenticator app, not just that it needs to be installed on your phone.
Either way, it's just Microsoft trying to push themselves into a space and remove consumer choice.
Is there another possible reason for this?
I'm saying that as a general fan of Microsoft. I just wish they'd stop doing these things that are not beneficial to the user, and solely focused on keeping themselves relevant.
The right way to stay relevant is to make great products.
microsoft seems to be acting like its in a death spiral, wringing everylast cent it can, and cutting as much overhead as possible, while reaching out to any possible investment bubble, and a daylate and a doller short everytime trying to ape contemporary successes of competitors.
now i understand why Bill cut the fetters and walked away from the board room.
So not great. But not terrible. Solid Dyatlov.
