Two-step sign-in on the account everything depends on

Turn on the one setting that stops somebody who has your password from getting into your email.

If somebody gets into your email, they do not need any of your other passwords. They can ask each of those companies to send a reset — to the mailbox they are already sitting in.

Two-step sign-in adds a second check to the password: a short code sent to your phone. Knowing the password stops being enough, because the phone is in your pocket.
