How to Protect Your Email from Breaches
Essential security practices to keep your accounts safe
Use Strong, Unique Passwords
Create complex passwords with 12+ characters including uppercase, lowercase, numbers, and symbols. Never reuse passwords across multiple accounts.
Enable Two-Factor Authentication
Add an extra layer of security with 2FA. Use authenticator apps like Google Authenticator or Authy instead of SMS when possible.
Use Different Email Addresses
Consider using separate email addresses for banking, social media, and shopping to limit exposure if one account is compromised.
Change a Password After a Breach
Change a password right away if it appears in a breach. Otherwise long, unique passwords and multi-factor do more than changing them on a schedule, which is what NIST SP 800-63B recommends.
Use a Password Manager
Tools like 1Password, LastPass, or Bitwarden securely store and generate strong passwords for all your accounts.
Beware of Phishing Attempts
Never click suspicious links or download attachments from unknown senders. Verify sender authenticity before sharing information.
Understand your email's exposure
Review your email's breach history and get clear, practical recommendations to strengthen your security.
