I personally am fine with this.
true. But I think that’s mostly to make bots harder to create. Not as easy to get a phone number than an email address
As the other commenter said, only if you give them your phone number, and only through that garbage authy that does not use standard TOTP, but some proprietary crap, specifically made for twitch.
And if you give them a phone number, which another user will also try to use in the future, then the secret used for TOTP can change in any moment, which means if you exported the secret to e.g. Aegis and deleted that tracking filled garbage that is named authy, at one point the codes just won’t work anymore, and you’re practically locked out. Apparently support should be able to help, but they don’t give a single fuck.
and only through that garbage authy
you can use any TOTP app. I use bitwarden
How? How do you import the secret key to it? Are they finally showing a proper QR code when setting it up?
My account is still locked to authy, and the support pages I have read are written as if it would still work through authy for everyone.
First of all, that they are totally unnecessary for twitch to be able to provide 2fa authentication.
Other than that, their app has tracker components, all secret keys are stored in the cloud, who knows whether that’s encrypted, but on your phone’s storage surely not, if yours is rooted you can just view it in a file manager and copy it to a normal code generator app.
Generally they support standard TOTP code generation, but for twitch they are using some weird shit that generates 8 long numbers (instead of the standard 6), of which the middle 2 is the same so they drop one of them, and then also codes expire in third the time as it is normally.
