GOOGLE: Hey, you signed in with your password! Ready for 2FA?
ME: Yep!
GOOGLE: Ok, I’ll send a code to your YouTube app, which you don’t even have installed, and even if you did have it you’d use it for silly things like watching videos instead of 2FA. I’m not going to send it to the TOTP app you’ve used every time for this task for years, unless you ask, yet again, to use that app.
