HumanCheck · for research on Alchemer

Every response from a real, unique human

HumanCheck locks bots and repeat humans out before they ever reach your study. About five seconds per respondent, two cents a verification, no code.

The check proves the respondent is live, present, and unique. Their one-time passcode fills itself in at your study’s gate; with auto-submit on, they never even see the login page.

1 A passcode per human

Each verified respondent receives a one-time passcode, created for their face alone and dropped onto their link.

2 Fakes locked out

A duplicate face never earns a second passcode, and a spent passcode is dead forever.
