What should I do after a data breach?

Discovering that your personal information has been exposed in a data breach can be concerning. Whether the breach involves an email address, password, phone number, or other sensitive information, taking prompt action can reduce the risk of further problems.

The first step is typically changing passwords associated with affected accounts. Users should also enable two-factor authentication where available and monitor accounts for suspicious activity.

Many breaches become public months after they occur, which is why periodic breach monitoring is a good security practice.

Key Takeaways

• Change affected passwords immediately.
• Enable two-factor authentication.
• Watch for suspicious account activity.
• Avoid reusing passwords.
• Monitor future breach notifications.
