Public username search
Check public username footprints with context.
WhatsMyName.io helps researchers check username and handle patterns across hundreds of public source definitions. Results are leads for manual review, not identity proof.

Built for responsible public-source research
The tool is intentionally narrow: it checks public profile patterns, organizes responses, and leaves the interpretation to the researcher.
Public data only
Checks are based on public profile locations and do not access private accounts or bypass login walls.
Source transparency
The supported source catalog is organized by category so you can understand coverage before relying on results.
Freshness controls
Snapshot timing is shown when available, and rescan lets you request a newer lookup when needed.
Cross-platform leads
Found URLs help you decide where to perform the next manual review, not whether an identity is confirmed.
Result filtering
Found, not-found, and category filters make large response sets easier to review.
Guided use
Documentation and ethics guides explain limitations, privacy boundaries, and safe investigation habits.
Frequently asked questions
Important limits before using username search results.
Is WhatsMyName.io legal to use?
Yes. The tool is designed for public-source research and only points to publicly reachable profile locations. Users are responsible for following local laws and platform terms.
Does a found result prove identity?
No. A username match is an investigative lead, not proof that accounts belong to the same person. Review each profile manually and cross-check context before drawing conclusions.
What information should I search?
Start with a public username or handle. Do not enter passwords, private tokens, or sensitive personal information that is not needed for a public-source check.
Read the methodology before relying on results
A username match is only useful when the surrounding context, risk, and ethical boundary are understood.
