How do I get the back up codes? I have set up Google authenticator in most of my apps and sites that require passwords to log in but I can't recall been given any back up code in case of phone loss or any other unfortunate circumstances. Is there any way I can go about to retrieve those back up codes now again?
Import your accounts to aegis by following the instructions below. I've personally done this and can vouch.
If you're planning on moving to aegis, it should be easy now with the 'transfer accounts' feature. To put it simply, google authenticator would generate a QR code which you can scan using your aegis app. Once done, all accounts should be transferred!
If you wanna see your backup/secret codes from aegis, press and hold any account > tap the pen symbol in your upper right > advanced > tick the eye symbol in 'secret'. But since aegis has a more efficient way of backing up, you don't really need to do this tedious way of backing up codes, I'd say it's optional.
