Audit and update existing passwords after a breach
5
Check if your email or passwords have been compromised using Have I Been Pwned (haveibeenpwned.com). Enter your email address and it shows which data breaches included your information. Change the password on every breached account immediately.
Why It Works
Billions of passwords have been leaked in data breaches. If you have used the same password on multiple sites, one breach exposes all your accounts. Checking and updating compromised credentials closes this vulnerability.
Tips
- Have I Been Pwned is a free, trusted service run by security researcher Troy Hunt
- Most password managers include built-in breach monitoring that alerts you automatically
- Prioritize changing passwords on email, banking, and social media accounts first
- After updating, enable two-factor authentication on every account that supports it
