I’m pretty pissed. A couple of months ago I configured Thunderbird to connect to Facebook’s XMPP-powered chat. I did get logged out sometimes, with mails from Facebook saying someone tried to access my account from an unknown location. Given the origin IP-address mentioned (in the private 10.x.x.x-range), this looked like a Facebook-internal problem (between their XMPP & Authentication servers).
Things have however taken a turn for the worse now; I’m not only getting logged out from Facebook on my 3 devices (work Win XP PC, home Ubuntu netbook & Android smartphone), I’m now even getting locked out of my account altogether, having to change my password on my smartphone (as that one has the OTP generator in the Facebook app). This happened 4 times in the last week and it is that frustrating that I disabled Facebook Chat in Thunderbird. And maybe that’s just what Facebook is aiming for; encouraging users to use Facebook Chat in a Facebook-owned/ -controlled context instead of in a neutral, ad-free 3rd party application? Wankers!
