But the short version is that using one password everywhere means that if just one site you use gets hacked, an attacker potentially has the password that unlocks your entire online life.
Hopefully, at this point everyone knows why it’s important to use a unique password for all of your accounts online. Basically, they take 90 percent of the work out of being safe online. A good password manager makes it easy to generate unique, strong passwords, and it will then securely save them so they’re available wherever you need them, whether that’s on your phone, laptop, tablet, or desktop computer. Using a password manager is one of the best steps you can take to protect your security online.
