If you're going to use a password manager, I would recommend 1Password or LastPass.

Other tricks you can apply:

- Use a different password on every website. To help you remember it, you can choose one main password and make variations on it for every website (the variation is based on that website, but don't make it too obvious!)

- I can't tell my password for a specific website if someone points a gun at my head, since I don't know it. I need a QWERTY keyboard to enter my password, because I only remember the flow of the characters I type. I don't remember all the characters.
