The most common solution is one-time-use backup codes that most services give you when enrolling. Hopefully you saved them somewhere safe! The main issue is Google Authenticator and how popular it is. As GP noticed, it doesn't flag the files as being allowed for backup which is kind of ridiculous. Almost anything is better, https://getaegis.app/ https://getaegis.app/ is my recommendation. You can also manually backup your seed (screenshot / save the QR code during enrollment).
