SKILL / Identity
Plans: Pro & AgencyPublic Username Discovery
Discover publicly documented usernames and handles associated with a named person, organization or project.
Read the step-by-step user guidePublic Username Discovery is the Nexus Skill for the question that comes before profile discovery: what usernames and handles is this person, organization or project publicly known by? Starting from a name, Nexus finds handles that public sources explicitly attribute to the subject — on profile pages, in bylines, in project pages and in published contact details — and grades each candidate by how well the evidence supports the attribution, so the investigator gains handles to pivot on without guessing.
What you get
Username and handle candidates attributed to the subject, each graded from supported to rejected, with evidence.
Using Public Username Discovery in an investigation
The result separates four kinds of candidate. Supported handles are documented in a source that names the subject directly. Possible handles match on a name or display name but lack a second confirming detail. Ambiguous handles could belong to several same-name subjects. Rejected handles were considered and set aside rather than silently dropped. Every handle keeps a link to the page where it was documented, and the investigator can open that evidence before deciding what to do with it.
Handles are among the most reusable identifiers in an identity investigation, which is why Public Username Discovery belongs early in an identity workflow. A supported handle can be passed straight to Public Profile Discovery or Extended Social Presence to find the accounts behind it, checked with Breach Exposure Search for authorized exposure records, or added to the relationship graph as an identifier linked to the subject. Ambiguous and rejected candidates stay in the case record, so the final brief shows what was considered as well as what was accepted.
Example objectives
Run the Skill directly, or describe the objective in your own words — these are the kinds of questions it is built to answer.
Ask Nexus
“Which usernames and handles are publicly documented for the founder of the project named in this case?”
Ask Nexus
“Find handles attributed to this organization across its public pages and tell me which ones are supported by more than one source.”
Ask Nexus
“Is the display name on this account attached to any documented username elsewhere, or is it too common to attribute?”
How Public Username Discovery fits the investigation
A Skill is one move inside a case. The findings stay in the case file, where the evidence behind them can be checked, graphed and reported.

Add to the case graph
Promote the people, organizations and identifiers you accept into the case relationship graph, straight from their evidence records.

Brief and report
Turn the case into a BLUF situation brief and, on Pro and Agency, into a structured PDF report with chain of custody.
Evidence before conclusions
What Public Username Discovery cannot establish
Nexus keeps supported findings, possible matches, contradictions and information gaps apart instead of blending them into one narrative. These are the boundaries Public Username Discovery states up front.
- Public Username Discovery does not enumerate private accounts and only reports handles that public sources explicitly attribute to the subject.
- A matching handle or display name does not establish identity without corroboration; Nexus grades such candidates as possible or ambiguous.
- If no documented handle is found, that is recorded as a gap in the available sources, not as evidence that the subject uses no handles.

Frequently asked questions
What is the difference between Public Username Discovery and Public Profile Discovery?
Public Username Discovery starts from a name and finds the handles that public sources attribute to that person, organization or project. Public Profile Discovery starts from a name or a handle and finds the profiles that may belong to it. The two chain together: Public Username Discovery produces supported handles, and Public Profile Discovery turns those handles into profile candidates. Both keep possible matches separate from supported associations.
Does Public Username Discovery guess likely usernames?
Public Username Discovery does not guess usernames; it reports only handles that are explicitly documented in public sources and attributed to the subject there. Nexus does not invent likely username patterns, and it does not treat a handle as attributed simply because an account with that name exists. That restraint keeps the result defensible: every handle in the report can be traced to the page that documents it, which matters when the finding ends up in a structured report.
Which Nexus plan includes Public Username Discovery?
Public Username Discovery is included on the Nexus Pro and Agency plans; Pro is €59 per month for 43 of the 47 investigative Skills and Agency is €89 per month for all 47. It matters most when the case starts from a name and the handles themselves still have to be documented; when a handle is already known, Public Profile Discovery can start from it directly.
Can Public Username Discovery be used for an organization or a project?
Public Username Discovery accepts a person, an organization or a project as its subject and reports the handles that public sources explicitly attribute to it — for example an organization’s official or support accounts, or a project’s published maintainer handles — each linked to the page that documents it. Where a source presents a handle as belonging to a named individual rather than the organization, that attribution is recorded as the source states it, so the investigator can judge whether it represents the entity itself.
