I personally am fine with this.
they want your phone number so they can track you.
Better to use an authentication app. SMS can be intercepted.
how would they track you?
The reason they want a phone number is, that it’s a relatively cheap way to ensure people not signing up bots galore, as getting phone numbers en masse is a lot harder than getting email accounts
phone numbers are typically tied to your name/identity, and phone companies can locate you using their towers and such. Giving a company your phone number is identical to giving a company your full legal name and address.
me giving, let’s say, twitch my phone number gives them exactly 0 ways of tracking me in any way whatsoever
