2FA with authenticator. As someone correctly points out, Google appears to keep SMS as a recovery option unless you specifically opt out?

Edit: I can't actually find a help article, but it's under "Try another way to sign-in" and they'll text you a verification code to your registered account phone number.

Just noticed that Authy’s answer to the FAQ of “ Is the Authy App Susceptible to a SIM Swap?” does not have the word “No” in it.

Does anyone know if Authy uses SMS for any kind of recovery? I don’t see an option in the security settings

SMS is just used to sign in. Everything is encrypted, and you can't access any data without a password. If you don't have the password, you don't get the data. There is no recovery.

Your OTP secrets should be e2e encrypted if you set up a backup passphrase. Worst case: someone can download your encrypted seeds.

I’ll agree though that Authy’s docs are really ambiguous about account recovery.
