 * Just wanted to report an issue. Today, out of the blue, my authenticator codes
   for both sites I have this plugin installed on did not match and would not allow
   me to login. I tried re-syncing the authenticator phone app to Google servers…
   the app said it was already in sync. I also tried deleting and re-syncing the
   authenticator app profile to the plugin… no luck. All of the other authenticator
   profiles I have on my phone are working, so I do not believe it is an issue with
   the authenticator app. It is only happening on the two sites I have this plugin
   installed on.
 * Up until now, it has been working perfect. There are no new plugins installed
   lately that might have caused a conflict. I even tried disabling my security 
   app [WP-Cerber] to see if that fixed it… no such luck.
 * Tried everything I could think of and finally had to disable 2FA on the backend
   via SFTP. Not sure if anyone else is having this issue, but just wanted to put
   the word out there.
 * Thanks

 * This could happen with time-based codes if the time on the web server is out 
   of sync.

 * Yeah, that could be it… my hosting company did some recent updates to the database
   server to resolve latency issues and kill some rogue processes. I tried reinstalling
   2FA today using my new phone that I just got. It sync’d up perfectly on the first
   try and works great… just as it did before this.
 * I wonder if the DB server latency issues caused the time sync issues. Seems likely.
