No, it's not the same with 1password, etc. (I'm assuming LastPass works the same way as 1Password - a master password protecting a local database of passwords).

No, it's not the same with 1password, etc. (I'm assuming LastPass works the same way as 1Password - a master password protecting a local database of passwords). My 1Password master password is useless without my database. If I accidentally typed it into Slack, I'd just change it in 1Password. This criticism does apply to all methods that use one master password to derive all other passwords. They necessarily have the master password as a single breaking point.
