Find Any Keybase Username with WhatsMyName App

Keybase is a security-focused identity platform where users cryptographically prove they control their accounts on other services. Because those proofs make Keybase one of the most reliable identity anchors online, searching Keybase through WhatsMyName App is a high-value OSINT step alongside 731 other platforms checked at the same time. No login, no install, results in seconds.

What Is Keybase and Why Username Searches Matter

Keybase launched in 2014 as a platform combining encrypted messaging with a public identity system built on cryptographic proofs. Users link their other accounts, such as GitHub, Twitter, and Reddit, by posting a signed proof, which Keybase verifies. Each user has a public profile reachable through keybase.io/username, which makes accounts directly verifiable by tools like WhatsMyName App.

Username searches on Keybase matter especially in identity verification and OSINT. Because Keybase proofs are cryptographically signed, the linked accounts on a Keybase profile are verified rather than merely claimed, which is far stronger than the self-asserted links on most platforms. Security researchers use Keybase to confirm that a set of accounts genuinely belongs to one person. Developers verify a contributor's identity with high confidence.

Because a Keybase profile provides cryptographically proven links between accounts, a confirmed result here is one of the strongest possible anchors in a cross-platform identity investigation.

How Keybase Usernames Work

Keybase usernames can contain letters, numbers, and underscores, are unique, and form the profile URL in the form keybase.io/username. The username is the account's public identity. The defining feature is the set of verified proofs on the profile, each cryptographically linking the Keybase identity to an account on another service.

Unlike the self-asserted links on most profiles, Keybase proofs require the user to post a signed statement on the linked service, which Keybase then verifies. This means a proven link on Keybase is a strong, tamper-resistant assertion that the same person controls both accounts.

Because users add and revoke proofs over time, real-time checks matter. WhatsMyName App checks the live Keybase profile each time you search rather than relying on cached data.

How to Search a Keybase Username with WhatsMyName App

No account, no install, no cost. Results in under 90 seconds.

Step 1

Go to WhatsMyName App

Open whatsmynameapp.us in your browser on any device. No account is needed and nothing needs to be installed.

Step 2

Enter the Keybase username

Type the Keybase handle into the search bar exactly as it appears in the profile URL.

Step 3

Run the search

Click Search. WhatsMyName App immediately begins checking all 732 platforms in parallel, including Keybase.

Step 4

Find the Keybase result

Results stream in as each check completes. Look for the Keybase entry showing confirmed or not found.

Step 5

Click through to verify

If confirmed, click the result to open the live profile and review the cryptographically verified proofs linking the identity to other accounts.

Step 6

Check connected platforms

Review all other found results, and compare them against the verified proofs on the Keybase profile, which confirm with cryptographic certainty which accounts belong to the same person.

Step 7

Export results

Once the scan completes, export all found accounts to CSV with one click, including platform name, profile URL, and category.

What WhatsMyName App Shows for Keybase

When WhatsMyName App finds a Keybase profile, it returns a direct link to it. Clicking through shows the username, public key, and the list of verified proofs linking the identity to accounts on GitHub, Twitter, Reddit, and other services, along with any verified websites. The profile confirms the username is registered and provides cryptographically proven links to the rest of the identity.

Keybase profiles are public, so a found result reliably indicates a live profile. If no Keybase profile exists for the searched username, WhatsMyName App returns a not-found result for Keybase while continuing to check all remaining platforms.

After Finding a Keybase Account

Once you confirm a Keybase profile, it becomes the strongest anchor in your investigation. The verified proofs on the profile cryptographically link the identity to specific accounts on other services, so you can confirm with high confidence which of the other results in the same search genuinely belong to the same person.

For developer or security identity verification, treat the Keybase proofs as authoritative: a proven GitHub or Twitter link is far stronger evidence than a self-asserted bio link. Use the proofs to validate or rule out the other accounts found.

If the search returned no Keybase result, the handle is not currently associated with a Keybase profile. The person may use a different username or not use Keybase, which is common outside security-focused communities.

Frequently Asked Questions about Keybase Username Search

What makes Keybase different from other identity platforms?

Keybase uses cryptographic proofs: users link their other accounts by posting a signed statement that Keybase verifies. This means the linked accounts on a Keybase profile are proven, not merely claimed, making it one of the strongest identity anchors online.

Why are Keybase proofs valuable for verifying identity?

A Keybase proof requires the user to post a signed statement on the linked service, so a proven link is a tamper-resistant assertion that the same person controls both accounts. This is far stronger than the self-asserted bio links on most platforms.

Does WhatsMyName App verify the cryptographic proofs itself?

WhatsMyName App confirms the Keybase profile exists and links to it. The cryptographic proofs are displayed and verified on the live Keybase profile, which you can review by clicking through.

What does a not-found Keybase result mean?

It means no public Keybase profile exists at the searched username. The person may use a different username or not use Keybase, which is common outside security-focused and developer communities.

Why might a Keybase search return an error?

An error means Keybase returned an unexpected response during the check, usually temporary rate-limiting or a brief connectivity issue. Wait a few minutes and run the search again.

Is searching a Keybase username with WhatsMyName App legal?

Yes. WhatsMyName App checks publicly accessible Keybase profile URLs, the same pages anyone can open in a browser. No private data is accessed. For the full legal context, see our guide on whether WhatsMyName App is safe to use.

How is this different from looking up a Keybase profile directly?

Looking up a Keybase profile shows that one identity and its proofs. WhatsMyName App checks Keybase and 731 other platforms at once, so you can use the verified proofs as an anchor and immediately see the wider footprint around the same handle.
