We know you’ve heard it before, but creating strong, unique passwords for all your critical accounts really is the best way to keep your personal and financial information safe. This is especially true in the era of widespread corporate hacks, where one database breach can reveal tens of thousands of user passwords. If you reuse your passwords, a hacker can take the leaked data from one attack and use it to login to your other accounts. Our best advice: use a password manager to help you store and create strong passwords for all of your accounts.
Then, check to see if your online accounts offer multi-factor authentication. This is when multiple pieces of information are required to verify your identity. So, to log into an account you may need to enter a code that is sent to your phone, as well as your password and passphrase.
