# Using Audience Authentication

> Give each audience member an individual passcode to join your presentation. Ideal for ticketed events. Available on Pro, Enterprise, and Edu Large plans.

The audience authentication feature lets you give out passcodes to your audience. Each audience member enters their individual passcode to join your presentation. This is especially useful for ticketed events.

<Note>
  This feature is only available on **Pro**, **Enterprise**, and **Edu Large** plans.
</Note>

## How does it work?

<Steps>
  <Step title="Open Audience authentication">
    Navigate to **Settings**, click **Audience authentication**, then tick the box **Require participants to enter authentication code**.
  </Step>

  <Step title="Set the number of participants">
    Enter the **number of participants your presentation will have**. If you don't know the exact number, it's better to overestimate so you'll have enough codes to give out.
  </Step>

  <Step title="Generate codes">
    Click the **Generate code** button. This downloads an Excel sheet showing all of your presentation's authentication codes.
  </Step>
</Steps>

From here, you can share one code per participant. After a participant accesses your presentation via the [URL link or QR code](/presenting/sharing-your-presentation-for-participants-to-join), they'll be asked to enter the authentication code in order to join.

<Note>
  Each authentication code **cannot be used** by two different participants at the same time.
</Note>

## Re-downloading your code list

If you need to download your code list again, navigate to the **Audience authentication** setting and click **Download authentication code list**. This gives you another copy of the code list containing all of your presentation's active codes (which remain active until you either reset or delete them).

## Resetting or deleting your codes

You can also reset or delete your codes in the **Audience authentication** setting:

1. **Reset your code list** by entering a new number of participants into the box and pressing **Generate code** again.
2. **Delete your code list** by clicking the **Delete generated codes** option.
