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?
Have a look at 2FAS. Open source. Works for me. 2fas.com
Second 2FAS, at least on iOS devices. I switched from Authy after Twilio got motherfucked the first time.
+1. Works well on Android as well. You can set up your Google Drive to store an encrypted backup of your private keys using a password you set. It also supports importing from other authenticator apps
Interesting option. Need to figure out if backups can be done without allowing access to iCloud.
