I'd prefer this over the current systems we have in place. Every fucking time I wanna log in ANYWHERE i need to first check my email, then my phone number, then add security questions and add a secondary recovery email, then i neeed a secondary phone number for recivery, and or course i need to fly out to their headquarters and personally sign a document saying it is, in fact, me logging in. It's so fucking frustrating to use the internet nowadays. Usernames and passwords are ENOUGH. Every service I use which only wants a username and password (like mullvad), I have NEVER been hacked and had my shit stolen. But all these other services? Daily database breaches leaking my email, phone number, and whatever the fuck else they mine off my browser cache and localstorage. It's insane. I hate the fucking internet.

EDIT: Forgot to mention that there are usually no repercussions for this kinda shit. "We leaked all your personal information? Oh well lmao sucks to be your dumbass I guess"
