Will changing password of a Google account revoke access to it on a lost device? I had a Samsung Galaxy Star Pro Duos with my Google account logged in to the apps (Google+, Gmail...). Now it is lost. I can remotely remove all my accounts from the web browser, but I do not know how to remove it from the device without having it turned on and sync enabled, as sync was disabled and it is currently switched off .

I was thinking if I change my password, my account on that phone would stop syncing and request for the password to be re-entered. Once someone turns it on, and tries to sync, the account must stop.

Will this plan work?
Changing your password will require all devices to reauthorize (log in) before syncing any new data, however information already on the device, like bookmarks and such, will remain.
Locking the device with Android Device Manager would be the better option.
