What Is WhatsMyName?

Whatsmyname is an open-source OSINT (Open Source Intelligence) tool that specializes in enumerating usernames across hundreds of websites and online services. Created by Micah Hoffman, this tool helps users discover where a particular username exists by querying a growing list of platforms—from social media sites to developer forums and marketplaces.

Instead of manually checking each site, whatsmyname automates the process, saving investigators valuable time while enhancing accuracy.

Why Username Enumeration Matters

Tracking usernames can reveal critical connections between online identities. Here’s why this matters:

• Digital Footprint Mapping: Understand how a person’s identity spreads across platforms.
• Link Analysis: Correlate accounts across services for investigative leads.
• Threat Intelligence: Identify fake profiles or malicious actors.
• Brand Protection: Monitor usernames that mimic corporate brands or executives.
• Content Attribution: Connect forum activity to public personas.

When used responsibly, username enumeration is a powerful starting point for larger digital investigations.

How WhatsMyName Works

Whatsmyname operates as both a website and a command-line script. It queries a curated list of sites using pattern matching and URL structures to determine if a given username is registered or active.

Here’s how it works:

1. Input a username into the interface.
2. The tool checks known URL patterns (e.g., twitter.com/username).
3. Based on the HTTP response (200 OK, 404 Not Found), it confirms if the username exists.
4. Results are displayed in a clear, exportable format.

For tech-savvy users, the script version allows deeper integrations and custom list management.

Key Features of WhatsMyName

• Easy Access: Web-based GUI and CLI (Command Line Interface) versions
