decrypt-otpauth-files VS Aegis

I used OTP Auth.app (https://cooperrs.de/otpauth.html) for many a while years on iOS and then on macOS too.

Now I've mostly transitioned to using the built in OTP handling in Keychain. Every so often I find one I haven't migrated across yet.

Another option is HE's NetWork Tools iOS app, which also has an OTP Authenticator in it. I believe it's a lot less integrated though (I don't think it provides a browser plugin, for example).

Forget all the cloud-based Authenticators and use OTP Auth. https://cooperrs.de/otpauth.html

I have been using OTP Auth for a while. It doesn't get updated a lot but it's working fine.

I do that using a separate app, (OTPAuth for iOS), and pretty much for the same reason.

OTP Auth Website

Good point. See also the developer's website: https://cooperrs.de/otpauth.html

Sure, that's a possibility. I believe it is developed by a single person. But the OTP Auth app allows you to export an encrypted backup that can be decrypted using an open source tool available here: https://github.com/CooperRS/decrypt-otpauth-files. Also, the OTP Auth app lets you view the original secrets (and display QR codes) used to create the TOTP entries. So it would be relatively easy to simply scan the QR codes with whatever new app you wanted to use in the future. In my book, that makes OTP Auth the safest option because I am guaranteed an easy way to migrate to a new app if I ever need to do so. ... Also, OTP Auth lets you have folders (in addition to searching), which is really helpful if you have a lot of 2FA accounts.

This is the best iOS answer. One of my most favorite apps. https://cooperrs.de/otpauth.html

For 1Password I use a Yubikey, but for 2FA in general, I have a backup phone running Aegis[1].

Bottom line is, why in the world would you use a mysterious closed source app when there are better options out there? 2FAS is one of the better ones. Aegis Authenticator is another good choice for Android devices.

You can enable 2fa with amazon I suggest you do that with a 2fa app like aegis, that will greatly increase the security of your account and require the 2fa code to login to your account.

Aegis Authenticator has been a lifesaver for me: https://getaegis.app/

I use Aegis[1] on mobile and OTPClient[2] on my computer, both are regularly backed up on change.

I do not use the TOTP feature in my password manager (though I can split it to new DB in keepassXC) as feel it will defeat the purpose of 2FA.
