Five steps, no code. 4 of 6Next: The respondent experience In Qualtrics, exactly as you normally would.
  1. Build your study as usual. Your questions stay exactly where they are.
  2. The gate is added in the **Survey Flow**, not on a page, so nothing about your instrument changes.

You now have: a normal Qualtrics study.

 In the VerifyYou dashboard.
  1. Click **New verification** and name the study.
  2. Under **"Where does your survey live?"** pick **Qualtrics**. That choice is how we know to create one-time codes in a contact-list file, the credential Qualtrics's own Authenticator understands.
  3. Paste your Qualtrics link and click **Create verification**.

You now have: your study link (the one you share, your Qualtrics link stays private) and a ready-to-import contact list holding one one-time code per verified respondent.

VerifyYou new verification screen, Qualtrics selected In Qualtrics's **Contacts** (called **XM Directory** on newer accounts).
  1. Click **Create Contact List** and import the VerifyYou file as-is.
  2. Each row carries one code in the **External Data Reference** field. That field is the passcode slot.

You now have: a contact list where each code can authenticate exactly once.

 Open your study's **Survey Flow**.
  1. Add an **Embedded Data** element at the very top, with the single field name `vy_code` and no value. Qualtrics then fills it from each respondent's link, their documented [query-string mechanism](https://www.qualtrics.com/support/survey-platform/survey-module/survey-flow/standard-elements/passing-information-through-query-strings/): the field should read "Value will be set from Panel or URL."
  2. Add an **Authenticator** element beneath it. Authenticate against your imported contact list on **External Data Reference**, tick **Prefill**, and point it at `vy_code`. Leave **"Allow authenticating respondents to retake authenticated section"** unchecked, which is the default: that is what makes each code one-time.
  3. Drag your survey blocks inside the Authenticator.
  4. After the Authenticator, add a **Branch** for anyone who falls through without authenticating, ending in its own **End of Survey** element marked as screened out. Qualtrics records a failed authentication as a complete by default, so this branch is what keeps failed and duplicate visitors out of your data.
Qualtrics's own [Authenticator](https://www.qualtrics.com/support/survey-platform/survey-module/survey-flow/advanced-elements/authenticator/) enforces the gate, and in their own words the Prefill option means a respondent with the right credentials "never even sees the authenticator."

You now have: a gate that opens itself for verified respondents and routes everyone else to a screen-out.

Qualtrics Survey Flow with Embedded Data element Qualtrics Authenticator with Prefill enabled Paste the study link from step 2 into your panel, your sample provider, or your invite email.

You now have: a fielded study where everyone who reaches your questions came through the check. That's the whole setup.

 **License note.** Free Qualtrics accounts do not include contact lists, so this flow needs a standard or university license, which is what most institutions provide. If the Authenticator element does not appear in your Survey Flow options, your Qualtrics brand administrator can enable it. ## What happens next
