Here are two quick tips that you can use to help protect yourself online:
Enable Multi-factor Authentification
MFA is adding a layer of security on top of your username and password. This is most commonly facilitated through your cell phone which receives a code via text or an MFA app when signing into your accounts. When logging in with an MFA-supported service you are prompted for this code which means without your phone, a hacker is unable to log into your account, even if they have your username and password.
Many services support MFA, such as email hosts, file sharing services, and social media sites. Visit https://twofactorauth.org/ to find out which sites are supported. By the way, MFA only takes a few minutes to setup.
Have you been “Pwned?”
“Have I Been Pwned” is a specialized search engine which allows you to check your email address against known data breaches to tell you if you have been affected. If your credentials have been breached, change your passwords right away and ensure that you have MFA configured.
Have I Been Pwned also provides an alerting service which notifies you if your email address shows up in future breaches.
