# The same mechanism, any platform

> One check, one single-use credential, enforced by whatever gate your platform already has. Alchemer today; the pattern fits anywhere.

Nothing about this is Alchemer-specific except the last step. The mechanism is always the same three moves, and only the credential changes shape to fit the platform's own lock.

<Steps>
  <Step title="The check">A quick face scan proves two things: a live person is present, and this face has not already been here for this study. Same check everywhere.</Step>
  <Step title="The single-use credential">Each verified human is handed a credential that works exactly once. This is the part that changes shape per platform.</Step>
  <Step title="The platform's own gate enforces it">We never need the platform's permission or an integration deal, because the enforcement uses a feature the platform already ships.</Step>
</Steps>

## What the credential looks like per platform

| Platform                     | The credential               | The platform's own lock                                                                                     |
| ---------------------------- | ---------------------------- | ----------------------------------------------------------------------------------------------------------- |
| **Alchemer**                 | A one-time password          | The Login/Password action, individual one-time passwords that deactivate after use                          |
| **Qualtrics**                | A single-use personal link   | Invitation Only mode: the link is the key, and it dies on first open                                        |
| **Typeform, Jotform, Tally** | A one-time token on the link | A hosted gate page opens the form only for a valid token, and a webhook removes anything that slips through |
| **Google Forms**             | A one-time token in a field  | A small script checks each submission and removes the bad ones                                              |
| **Your own survey stack**    | A one-time token             | Your code asks us "is this token real and unused?" before saving                                            |

The strength of the lock varies a little by platform, which is exactly why we start with Alchemer: its password gate is enforced by Alchemer's own server before a single question shows, the strongest no-code gate of any major survey tool.

## Where this matters

The same gate works anywhere paid responses attract fake ones:

* **Academic research.** Grant-funded studies where one duplicate respondent can poison a dataset, and where methods sections need a defensible answer to "how do you know they were real?"
* **Market research firms.** The screener criterion your clients are quietly asking about: are they a person, and are they unique?
* **Panels and communities.** One verified human per panelist, so incentive fraud stops at signup instead of in your data cleaning.
* **Brand trackers and repeated waves.** Uniqueness holds per wave while honest panelists breeze back in, so wave two fields faster and cleaner than wave one.
* **B2B and expert interviews.** High incentives attract professional fakers; a face that can only qualify once ends the repeat-expert problem.
