Most 2FA is associated with a phone number (technically "something you have"). Tesla uses an authenticator app - the one MS made is good because it can backup to iCloud on iPhone AND has a recovery email account. Authenticator is much safer than cell phone number as it can't be "stolen" from you by social engineering with the provider.No. That would not be true two-factor then.
Something you know and something you have.
As for getting around the 2FA, when you created it, it gave you a long set of numbers/letters that were supposed to kept safe. I know this can be used because I see it on the website as "Verify another way" - it then asks for your backup key. If you do not have this, you are in trouble.
