Bad people love it when you use the same simple password for everything. “But I can’t remember a bunch of different passwords”. Then don’t… use a secure password storage application like Ewallet or a service like LastPass or 1password, which allows you to remember only one strong* password. Within the app you can use and store very strong passwords. Password applications have features like one click log-in to sites, password generators and the ability to access via mobile phones. With LastPass, you can add secondary authentication using a YubiKey or a software authenticator.
*(Strong Password = at least 16 characters - upper and lower case, numbers and one special character - *&^%#$@).
Best to do a sentence like "MakeAPasswordLikeThis2!" is stronger than "d@534kadA*"
Change your master password frequently.
