Starting yesterday, Gmail in Chrome is displaying a popup saying
"Authentication Required" and requesting a username/password. This
behavior is unique to Chrome - doesn't happen in Firefox or IE. It's
also apparently unique to my home laptop. It's not happening on my
work computer. I've been using Gmail in Chrome since the first day it
was available without issue until now.
The behavior began after many hours of having Gmail running - all of a
sudden I start getting this popup. I am reluctant to actually supply
a username/password, thinking this might be a phish. The popup
doesn't interfere with being able to use Gmail - it just won't go
away. It's really obnoxious.
1) is this popup being generated by Gmail/Chrome or is it malware?
2) is there a fix or workaround?
