Defender is a fantastic security plugin and I love that is has 2FA built in. Authy is a fantastic 2FA service, similar to Google's, and it would be great to see Defender support Authy as an option to handle 2FA.
Currently using Authy with Defender causes a log-in loop that is inescapable if you reset the session expiry time. Authy waits for the Approval from the Phone App, and when it tries to login Defender brings it back to the log-in for saying session has expired. Almost all of my websites use Authy to control access so I can't use Defender on those websites. Please add in Authy support!
