What does WhatsMyName do?

WhatsMyName allows users to quickly determine whether a username appears across multiple online platforms.

It performs automated checks against a curated database of sites and returns possible matches, confirmed accounts, or unavailable results.

The lowdown: The tool is a quick and effective way to identify where a username may appear online, particularly useful in the early stages of an OSINT investigation. However, results should always be treated as potential matches rather than confirmed accounts.

How to Use:

Go to the WhatsMyName website.
Enter the username into the search field. E.g. We typed in OSINT Industries.

Run the search and wait for the scan to complete.
Review the list of websites where the username appears. Results present in icons on the left (highlighted in Green) as well as in a searchable table on the right.
Manually verify accounts to confirm they belong to the target individual.

Some platforms block automated detection.

Summary

WhatsMyName is a fast and accessible OSINT tool for username discovery across multiple platforms. It’s particularly valuable during the initial stages of online investigations, helping analysts identify where a username may exist online and where further investigation should be focused.

However, results should always be manually validated, as usernames alone are not sufficient to confirm identity.
