# Two-Person Unlock

Two-Person Unlock increases door security by requiring two authorized users to present valid credentials within 10 seconds of each other before access is granted and the door is unlocked.

{% hint style="danger" %}
When two-person unlock is enabled on a door schedule, certain unlock methods are restricted:

* **Bluetooth unlock** is disabled for all users, including users in exempt groups.
* **Remote unlock** is disabled for all users, except users in exempt groups.
  {% endhint %}

## Configuration

You can enable the two-person unlock setting on [door schedules](https://app.gitbook.com/s/aaHs5RfKqv9Z49mi02cC/configuration/door-schedules-and-exceptions) during time periods when the Door Status is set to access-controlled.

{% stepper %}
{% step %}
**In Verkada Command, go to All Products > Access.**
{% endstep %}

{% step %}
**Under Doors, select the door you want to configure.**
{% endstep %}

{% step %}
**In the top right, click Schedule.**
{% endstep %}

{% step %}
**At the top left, next to Door Schedule, click** <i class="fa-gear">:gear:</i> **> Edit Current Schedule.**
{% endstep %}

{% step %}
**Set the start and end times of the schedule and select one or more days of the week on which the schedule should be applied.**
{% endstep %}

{% step %}
**Next to Advanced Settings, click Show all.**
{% endstep %}

{% step %}
**Toggle on Two-Person Unlock.**

a. **Exempt groups** **-** Members of these groups can unlock the door without a second user.\
b. **Required groups -** At least one of the two users must belong to one of these groups to complete the unlock.**Note:** Users in exempt or required groups must still be granted door access through an assigned access level to unlock it. See [Assign a User Access to a Door](https://app.gitbook.com/s/aaHs5RfKqv9Z49mi02cC/users-and-credentials/add-a-user-to-the-verkada-access-system/assign-a-user-access-to-a-door) for more information.
{% endstep %}

{% step %}
**Click Done.**
{% endstep %}

{% step %}
**At the top right of the page, click Save.**
{% endstep %}
{% endstepper %}

## Use two-person unlock

{% stepper %}
{% step %}
**When the first user presents their credential on the door reader. One of three outcomes occurs:**

* **Standard Flow:** If the user has access (and is not exempt), a 10-second timer begins, and the reader waits for a second credential.
* **Access Denied:** If the user does not have access to the door, the reader will immediately display a red LED.
* **Exempt User:** If the user has access and is in an exempt group, the reader shows a green LED and the door unlocks. The two-person rule is bypassed.
  {% endstep %}

{% step %}
**A second, unique user must present their credential within the 10-second window. One of three outcomes occurs:**

* **Success:** If the second user’s credential is valid, the reader shows a green LED and the door unlocks.

  **Note:** If required groups are configured, at least one of the two users must belong to a required group. If both users are valid but neither is in a required group, access is denied, and the reader shows a red LED.
* **User with No Access:** If the second user does not have access to the door, the reader shows a red LED, and access is denied for both users.
* **Timeout:** If no second credential is presented within 10 seconds, the attempt times out and the reader shows a red LED.
  {% endstep %}
  {% endstepper %}

To retry after a failure or timeout, the process must restart with the first user presenting their credential again.
