BitWarden is a powerful and free password manager.
You should be using new and unique passwords for every online account you have.
I know that sounds difficult and annoying, but a password manager can make your life easier.
Watch this video and then get one. I suggest BitWarden from personal experience. This is not an ad or sponsorship.
I just use it and love it. There are some other good ones but just be mindful and use a reputable company. Using any password manager (KeePassX, LastPass, 1Pass, Dashlane) is better than nothing. Give BitWarden a look and save yourself time and energy while increasing your safety at the same time.
