Google/Talk

Not Authorized
When I try to connect my pidgin to my gtalk account I get the following error: Not Authorized

Assuming your username/password are correct, this is probably caused by the following security setting:

Log into http://accounts.google.com/ Then under the "Signing In" section I chose "Access for Less Secure Apps". It was disabled, and once I enabled that option, Pidgin was instantly able to connect.
