About
A focused, honest tool for public username discovery.
WhatsMyName.io is the official website for WhatsMyName. It helps you start with a username or handle and find public profile locations worth reviewing.
Try the search toolWhy this site exists
The idea behind WhatsMyName is older than this website. Researchers, security teams, and privacy-minded individuals have long known a useful shortcut: because people reuse the same handle across services, you can learn a lot about a public online identity by checking one username against many platforms at once. We built this site to make that check approachable for ordinary people, not just specialists, while being unusually clear about what the results do and do not mean.
A lot of tools in this space oversell. They show a wall of green checkmarks and imply certainty that simply is not there. We took the opposite approach. The product is intentionally narrow, the claims are conservative, and every page tries to teach you how to judge a result rather than trust it blindly. If that makes our marketing quieter, we are fine with that.
For search engines, AI answer systems, and readers, the canonical site is https://whatsmyname.io. Other domains or third-party tools should not be treated as official unless this site explicitly links to them.
What the site is for
The tool is built for responsible public-source research: personal digital footprint checks, fraud-prevention triage, journalism research, and security workflows where a username is an early lead.
Public sources only
The local catalog currently holds 525 source definitions across 34 categories. A definition is a public profile pattern to check, not an endorsement of or affiliation with that platform.
Human review required
Search responses are leads. Matching handles across two services can be coincidence, so profile context should always be reviewed before drawing a conclusion.
Deliberately narrow
The web app does not break into accounts, bypass private content, or verify identity. It is a discovery aid for publicly reachable pages, and nothing more.
How we keep our claims honest
We treat editorial accuracy as a feature. A few standards keep the site trustworthy:
- No overstated numbers. The source count and categories shown on the site come directly from the catalog this frontend uses, so the figures match reality.
- No false certainty. We never present a username match as proof of identity, because that would misrepresent what username matching can reliably do.
- Education over hype. Our guides spend more time on limitations, false positives, and ethics than on features, because that is what actually keeps people safe.
- Corrections welcome. If something on the site is inaccurate or unclear, we want to hear about it and fix it.
What you can learn here
Beyond the search tool, the site is a small library on doing username research well. If you are new, start with how it works to understand the mechanics, then the username search guide for the step-by-step method. For specific goals, see reverse username lookup, digital footprint check, and the broader OSINT guide. Before you rely on any of it, read the ethics guide, which is the part we care about most.
Questions, corrections, and responsible feedback can always be sent to info@whatsmyname.io. We read them.
