We recommend people use a password keeper like LastPass, Dashlane, or a product we use called 1Password to generate, store and retrieve passwords. These password keepers also help you create secure, randomly generated passwords.
First, ensure your hard drive is encrypted. If you’re using a Mac, that means having your FileVault enabled, and on a PC, it would likely be BitLocker. If your computer is stolen, all of the data on your computer is encrypted (or scrambled) and unusable to someone else.
