Where does your username exist online?

Enter a username and we automatically check 30+ platforms — social media, developer sites, messaging apps, and more. See your digital footprint, assess your exposure, and find accounts you may have forgotten about.

Search Your Username Across the Web

Enter a username to discover which platforms it is registered on. This helps you understand your digital footprint and identify forgotten accounts that could be a security risk.

We only check if a username profile page returns a public HTTP 200 response. No login credentials are tested, no accounts are accessed, and no data is stored.

Username hygiene tips

1.Use different usernames for sensitive accounts (banking, email) and public ones (social media, forums).
2.Delete or deactivate accounts you no longer use. Dormant accounts are prime targets for takeover.
3.Never reuse passwords across platforms, especially those sharing the same username.
4.Enable two-factor authentication on every platform that offers it.
