Phone-number-based two-factor authentication almost locked me out of my PayPal account. The account was registered to my home phone in Canada, but I was traveling in Asia. When I tried to log in from my seemingly suspicious new location, PayPal required a confirmation by calling my number and announcing some digits. Very fortunately my home phone used Voip.ms, so I was able to log on to that account and redirect the call to the physical phone I had on hand. Ideally I would decline phone 2FA because my home phone or cell phone number could become unusable and lock me out of accounts.
