For LastPass we recommend also using a Yubikey. It’s like having an uncrackable master passsword that only you possesses. Get two, register both with LastPass and keep the other in a super safe place in case you lose your first one.
One other tip is to use Chrome’s multiple users feature. That is, create a Chrome user for each client/projects and then you can stay logged in to the accounts specific to each (instead of logging in and out and in and out.)
p.s. There’s a typo where you mention WordPress.
