Good evening,
Please re-download the google authenticator app and re-scan the QR code or enter the time based code to obtain the token to login to your account.
If you do not have access to the QR code (the bar code you scanned when turning on authentication) or the time based code, then a ticket must be created to begin the process to turn authentication off from your account.
Please see https://forum.xat.com/requests/open-a-ticket/?do=form and request a ticket for "Lost Authentication" - enter your xat username, ID, and put the e-mail associated with the account.
A ticket will be opened by a volunteer and you will receive an e-mail notification when a response is made on your ticket.
For more information regarding account authentication, please see https://util.xat.com/wiki/index.php?title=Authentication
If you need further assistance, please reply to this thread or visit xat.com/Help and someone will be glad to help you!
