Every week another large company has a data breach. One way to help protect your accounts is to have a different password for every account. This is HARD to do!
A password manager is a great way to have one master password and then have your others in an encrypted vault that travels with you between phones, browsers, etc.
Create an account and install the browser extensions or try the full Windows client. Then save a few passwords to it, and generate a new and difficult password for them.
