Sign up for data breach alerts
When a website is breached, attackers often obtain email addresses and passwords and then try those same details on banking, email, and social media accounts to see what else they can get into. Being alerted as soon as your email appears in a breach gives you time to change passwords and secure accounts before an attacker tries them.
Why this matters
When a website is breached, attackers often obtain email addresses and passwords and then try those credentials on banking, email, and social media accounts in a technique called credential stuffing. Being alerted as soon as your email appears in a breach gives you time to change passwords and secure accounts before an attacker tries them.
How to do it
- Go to haveibeenpwned.com.
- Enter your primary email address in the search box to see if it has already appeared in any known breaches.
- If any breaches are shown, change the password for the affected service immediately — especially if you reused that password elsewhere.
- Click 'Notify me' and register your email address to receive future breach alerts.
- Repeat for any secondary email addresses you use for important accounts.
