Authy is a nice alternative to google's Authenticator

Was bought by Twilio, but still rocking.

I love the plugin for raycast.app for it

You set a master password and can login back with your phone number/master password in any device

Much easier to not fuck up 2FA with it when changing phones

FreeOTP is another alternative - passphrase-encrypted backups can be saved to local or cloud storage and imported to FreeOTP running on another device.
