Securing Your Accounts

Attackers can use credential stuffing to test username/password combinations. Attackers will use information from one hacked site to infiltrate accounts on other sites.

To protect yourself you should never:

  • Use weak passwords
  • Reuse passwords

Using Multi-Factor Authentication (MFA) can make your accounts even more secure, even if your password is compromised.
