TL;DR: Last Pass is broken. All passwords at the time of the breach were taken. They also got internal secrets from a laptop and can now probably throw computational power at anything they want to decrypt.
Switch. Do not use. Change everything you have if you were using it. Treat everything as breached.
No? All your passwords absolutely should be randomly generated and unique per website, something you can't keep track of on your own. The solution is a password manager that syncs to all your devices.
