Xat, possibly in an effort to prevent the phishing of email accounts, appears to have made a change to their login system. A quick visit to the Xat login page shows the following change (see pic).
Users will find that the traditional “email/password” login has been replaced with a new “xat name/password” login.
Oddly, at the time of this post, we were able to login using either our email or xat name. Xat may be slowly transitioning to the new system; we’ll just have to wait and see.
