I’m also not a fan of MS spyware.
But in defence of the MS authenticator, the 2FA prompts it sends are very convenient, how they pop up and ask for the number displayed on screen, its definitely more secure than just the one time code.
Plus it also shows what phone the user is using when they install and configure the authenticator app, this is also very useful if you suddenly see the user accessing their mail or one drive from another mobile device.
Some real digital history record keeping there! This stuff is so cool and is something we never considered with all those random memory cards we gave away and sold.
I’m so jealous.
