RETURNING PARTICIPANT

Sign in to your registry workspace

Use the pseudonymous participant ID and registry access key you saved when you joined. The Registry does not require an email address for participant access.

Privacy note. Your participant ID identifies your Registry record, but it is not a password. Your access key is the secret credential that restores access to your workspace. Do not share it publicly.

New to the Registry?

Create a pseudonymous participant ID and private access key. Research participation remains optional.

Joined before access keys were displayed?

Earlier Registry versions stored participant access only in the browser. If this browser still has that valid legacy session, you can upgrade it and receive a key you can save.

Check this browser for legacy access

Lost your access key? The Registry intentionally does not use email or identity-based public recovery. A participant ID alone cannot safely reset access. If no signed-in or legacy browser remains available, the stored hash cannot be reversed.

Registry administrator?

If you are recovering an older test or participant record that never received an access key, use the protected administrator recovery flow.
