TikTok signs users in with their TikTok account. It fits creator tools and consumer apps whose audience arrives from TikTok in the first place.

## Copy the redirect URI

In the [Authdog console](https://console.authdog.com), select the project and environment, open **Authentication > Providers**, find **TikTok**, and click **Enable**. Copy the redirect URI shown in the form:

```url
https://identity.authdog.com/api/v1/callback/<connectionId>
```

## Create the TikTok app

1. Open the [TikTok for Developers portal](https://developers.tiktok.com/apps) and register an app.
2. Complete the app details — name, icon, category, description, and the terms and privacy URLs. TikTok checks these during review.
3. Add the **Login Kit** product.
4. Under **Redirect URI**, paste the redirect URI from Authdog.
5. Request the `user.info.basic` scope.
6. Submit the app for review, and wait for approval.
7. Copy the **Client Key** and **Client Secret**.

> **Caution**
>
> TikTok gates production access behind review. Before approval, only accounts
> you have added as testers can sign in. Budget for the review turnaround in your
> launch plan — it is the longest lead time of any connector here.

## Configure Authdog

| Field | Value |
| --- | --- |
| **Client ID** | The TikTok **Client Key** |
| **Client Secret** | The TikTok **Client Secret** |

Save, then toggle the connection **active**.

## What TikTok returns

Authdog requests `user.info.basic` and reads the profile from `https://open.tiktokapis.com/v2/user/info/` — an open ID, display name, and avatar.

No email address is available at this scope, and TikTok does not offer an email scope for Login Kit. Users arriving through TikTok have a display name and an identifier only, so pair this connector with one that provides a contact address, or ask for an email after sign-up.

TikTok's identifiers are app-scoped: the same person authorizing two of your apps produces two different open IDs.

## Test it

1. Add your test account under the app's tester list if the app is still in review.
2. Open your environment's hosted sign-in page, or link to `https://identity.authdog.com/api/v1/signin/<connectionId>`.
3. Select the TikTok button and authorize.
4. Confirm the user appears under **Users**, with no email — expected for this connector.

## Troubleshooting

| Symptom | Cause |
| --- | --- |
| `redirect_uri` error before the consent screen | The URI is not registered on the app, or the app is not approved |
| `invalid_client_key` | The client key belongs to a different app or environment |
| Only some accounts can sign in | The app is pre-review and limited to listed testers |
