When setting up 2FA, the services typically give a list of recovery codes which you hopefully still have. With those, you can gain access and link other 2FA devices. If you have the recovery codes and got access again, then you can get a bit more redundancy in your system by also setting up security keys such as a Yubikey. These keys can be added next to your authenticator app(s).
