If you suspect your Mozilla account has been compromised or just want to perform a security check-up, it’s important to take the right steps. This guide explains how to review your Mozilla account activity, change your password, review account activity, and enable two-step authentication. You’ll also learn how to check for data breaches using Mozilla Monitor to enhance your overall security.
Where can I see my recent account activity?
There are a couple of ways you can check your account activity:
- You received an email from accounts@firefox.com detailing a recent sign-in event or product access.
- You will receive this email whenever your account or a product is signed into for the first time on an unrecognized device.
- You can view recent activity on your Mozilla account by visiting your Mozilla account settings page and selecting .
What action should I take?
Change your Mozilla account password
Changing your password ensures no one can access your account with old credentials. It also signs you out from all devices and services to protect your data.
- Sign in to your Mozilla account and, next to Password, select to update your password.

Monitor connected services for unauthorized access
Regularly reviewing the devices and services connected to your Mozilla account helps identify and address unauthorized activity.
- Sign in to your Mozilla account and scroll down to the Connected Services section to see all logged-in devices and services.Tip: After resetting your password, this list should only show devices you’ve logged into since the reset.
- Remove unrecognized devices. If you spot suspicious entries, click the button next to that entry.
Enable two-step authentication
Adding two-step authentication to your account provides an additional security layer by requiring a second verification step, making unauthorized access much more difficult.
- Sign in to your Mozilla account and enable two-step authentication in the security section to enable this feature.
- Set up an authentication app. Use a trusted app like Google Authenticator or Authy to generate codes for signing in.
- For more information on enabling two-step authentication, see the Secure your Mozilla account with two-step authentication article.
Check for data breaches with Mozilla Monitor
Mozilla Monitor helps you discover if your email address has been exposed in a known data breach. Taking action based on this information can help you secure your other accounts as well.
- Visit https://monitor.mozilla.org and enter your email address to scan for known exposures. Exposures are events where log-in credentials from other websites may become publicly shared through a breach of security.
- Review breach details. If your credentials were exposed, update your passwords for affected services immediately.
