Hi, wondering if I had a device lost or stolen if there's a way I could prevent synching of new data to that particular device (deauthorizing and/or changing security key)? My reasoning is that if my device were lost/stolen I could technically change all my passwords (or at least the important ones) so that even if the thief was able to successfully hack the data on my device (although unlikely), the passwords would be useless to them. But it would be pointless to change my passwords if the new/updated passwords would automatically synch to the stolen device.
I understand that changing the security key would not prevent a password brute force attack since the old key could be cached, thus the master password would be the only line of defence. Also the thief could prevent a deauthorize command simply by keeping the device off-line (but that would also prevent synching too of course).
I know a hack is unlikely provided we use a strong password, but just exploring ideas to be extra secure in a worst case scenario.
