Use a Password Manager
Password managers are one of the most effective security tools available. They generate, store, and autofill strong unique passwords for every account, eliminating the need to remember dozens of complex passwords.
Choosing one
Whichever password manager you use, protect it with one strong password that you use nowhere else, and turn on two-factor authentication for it.
