It’s been a long time since I set it up, but I have Microsoft accounts in my usual TOTP app (Aegis). Maybe I did it manually? But it’s definitely possible.
One of the great things about Linux is that you can almost always just run whatever distro from the USB drive before installing (and just reboot without the USB drive to get back into Windows) So you can download a few ISOs and try each one for a bit before committing to anything.
This is nice if there’s anything specific that you need to work, you can try it and make sure it’s usable for you before making any permanent changes.
For example, I’m legally blind and use a screen magnifier. I tried a few distros to compare the built-in magnifiers before settling on one.
I’d also recommend using Ventoy on your USB. That lets you just plop ISO files on the drive and choose which one at boot.
It should be like music. You can sign up for basically any service (Spotify, YouTube Music, Apple Music, etc) and generally hear any song. It would be ridiculous if each record label or whatever had its own streaming service, so why are TV & movies different?
Occasionally I’ll go to a subreddit on mobile browser and half the time I can’t view it due to mature content. If I really care then I’ll go to old.reddit but often I’ll just back out.
