I have received reports from a couple of other folks that
authentication fails for them. The only cases where this happens is
when "special" characters (e.g. +, *, etc...) are part of the
password. They are -- obviously -- valid characters, however I need to
handle them properly when sending them to Google for authentication.
The next versions of the plugins will hopefully address this. I expect
to release new versions this summer.
Sorry for the troubles and thanks for your report.
