I know that, from a security perspective, using the same password for more than one website is a bad idea. However, I have a situation where I need to do that (the SE sites I have accounts on).
On *.stackexchange.com, I can use the same password entry across subdomains. However, for the older SE sites that have separate domains (SO, SU, SF, AU), I need to keep and update separate password entries in LastPass, which is annoying. Is there a way to group these sites, so that changing my password for stackexchange.com will automatically change it for SO, SU, etc.?
