Microsoft Authenticator needs your phone number and sends data back to Microsoft. If you're on Linux, macOS, or similar, there's a simpler way! oathtool does the same 2FA job, right from your terminal, and keeps your info private. Use oathtool command line for 2 step verification (2FA) https://www.cyberciti.biz/faq/use-oathtool-linux-command-line-for-2-step-verification-2fa/
@nixCraft I hope FreeOTP is useful too 😱
@cruiser @nixCraft or e.g. aegis. Or any other free (beer and freedom) application that supports the Standard - TOTP.
Microsoft just tricket uninformed users and #windowsadmins into thinking a backchannel would be good.
@holgersson @cruiser @nixCraft Since the OP was referring to a CLI for TOTP, I'm assuming the topic was solution for desktop/laptop use. Aegis only exists as an Android app, doesn't it?
@internic @cruiser @nixCraft ...totally correct! Mea culpa.
