another security measure I'd love to have anywhere, specially on google, would be setting up a secondary password with restrict access (i.e. not being able to change passwords) so I can use it anywhere I consider not safe (i.e. not on my machine) which will keep at very least my strong and most important password safe (which is enough for me). I wonder why I've never seem this done anywhere so far!
