It’s time for me to move from SMS to a 2FA Authenticator app. I want something that will be open source but also ridiculously easy to back up, transfer to a new device, or replace if it is on a device that fails. I want it to be versatile enough to use across all necessary authentications. I also want to be sure that I can use the same app for many many years. I don’t want it tied into another service.
What’s my best option?
Yeah it is great. It is too bad that it’s not maintained anymore, but besides compatibility issues with new phones like you mention, I really have no reason to pick a new app if the one I was using for years still works.
