WeChat

Allows users to authenticate using their WeChat credentials by configuring WeChat as a federated identity provider via OAuth2.

Preparation​

The following placeholders are used in this guide:

  • authentik.company is the FQDN of the authentik installation.

WeChat configuration​

To integrate WeChat with authentik you will need to register a "Website Application" (网站应用) on the WeChat Open Platform.

  1. Register for a developer account on the WeChat Open Platform.
  2. Navigate to the Management Center (管理中心) > Website Application (网站应用) and click Create Website Application (创建网站应用).
  3. Submit the application for review.
  4. Once approved, you will obtain an AppID and AppSecret.
  5. In the WeChat application settings, configure the Authorized Callback Domain (授权回调域) to match your authentik domain (e.g. authentik.company).
info

This integration uses the WeChat "Website Application" login flow (QR Code login). When users access the login page on a desktop device (Windows/Mac) with the WeChat client installed, they may see a "Fast Login" prompt.

authentik configuration​

To support the integration of WeChat with authentik, you need to create a WeChat OAuth source in authentik.

  1. Log in to authentik as an administrator and open the authentik Admin interface.
  2. Navigate to Directory > Federation and Social login, click Create, and then configure the following settings:
    • Select type: select WeChat OAuth Source as the source type.
    • Create OAuth Source: provide a name, a slug (e.g. wechat), and set the following required configurations:
      • Protocol settings
        • Consumer Key: Enter the AppID from the WeChat Open Platform.
        • Consumer Secret: Enter the AppSecret from the WeChat Open Platform.
        • Scopes: define any further access scopes.
  3. Click Finish.
Display new source on login screen

For instructions on how to display the new source on the authentik login page, refer to the Add sources to default login page documentation.

Embed new source in flow Enterprise

For instructions on embedding the new source within a flow, such as an authorization flow, refer to the Source Stage documentation.

Source property mappings​

Source property mappings allow you to modify or gather extra information from sources. See the overview for more information.

The following data is retrieved from WeChat and mapped to the user's attributes in authentik:

WeChat Fieldauthentik AttributeDescription
unionid (or openid)usernameUsed as the primary identifier.
nicknamenameThe user's display name.
headimgurlattributes.headimgurlURL to the user's avatar.
sexattributes.sexGender (1=Male, 2=Female).
cityattributes.cityUser's city.
provinceattributes.provinceUser's province.
countryattributes.countryUser's country.

User Matching​

WeChat users are identified by their unionid (if available) or openid.

  • UnionID: Unique across multiple applications under the same developer account. authentik prioritizes this as the username.
  • OpenID: Unique to the specific application. Used as a fallback if unionid is not returned.
info

WeChat does not provide the user's email address via the API.
