Authentication libraries: Two factor auth support

Thanks for the responses.  After a bit of hunting around I found a fork of Ion Auth 2 that includes TOTP and have just had a quick play around with it and all appears to work well: https://github.com/SpyTec/CodeIgniter-Ion-Auth-OTP

It's for IonAuth2, not 3.  At some point I might look at integrating it with IonAuth 3 as don't think 2 is wildly different to 3.

Hi jhob,

If the library suites you requirements you should go for it. I don't think CI2 and CI3 are that different. Certainly not like CI3 & CI4. If you should have questions concerning ION Auth, you can find info on stackoverflow. Ben the creator of Ion Auth is very nice guy, and will also help you if you post questions about the library on the GitHub page. There is some info about 2fa on the GitHub issue section of the library awell. Good luck!
