> The central access to almost everything in my life is my Gmail account This is a problem, you really do not want to rely on Google for everything. Not just because of the possibility of getting locked out due to e.g. theft, but because Google might shut your account down at any moment (I know several people whom this has happened to) or getting compromised. > My biggest fear is having my cellphone stolen and, when I try to access my Gmail account from my laptop, not being able to do so for some reason and getting locked out forever. You can generate backup codes for your Google account, store them somewhere at home (I have mine in a safe). Regarding Google Authenticator, there is a way to export the TOTP secrets, so print them out also and store them somewhere (or maybe KeePassXC with the vault stored on a USB stick?)
