Don’t even remember why I chose it, but remember everyone being very happy about it. Here’s the info from it’s FAQ:
Compared to other 2FA apps, we think Aegis stands out in terms of its simplicity and security. Most popular apps like Google Authenticator and FreeOTP don’t bother with additional security measures. They allow access to your tokens right after opening the app. Aegis, on the other hand, encrypts all of your tokens at rest and requires a password or the touch of a finger to decrypt them.
Another important feature is the ability to export your tokens and import them into another device. Google Authenticator doesn’t have this, which has not only annoyed users for years, but has also resulted in loss of access to lots of accounts.
Take a backup once every 6 months or so, and have it on my computer. Along with my backup of password manager’s file.
As a last resort, I just remember my email account’s password and keep it’s backup codes with me, everything else can be reset as long as I can log into my email account.
