Auth0

Follow these steps to add Auth0 as a social sign-in provider to your project using the Ory CLI:

Create an Auth0 Application for your Auth0 Tenant.

In the created app, set the redirect URI to:

https://{project.slug}.projects.oryapis.com/self-service/methods/oidc/callback/auth0

Create a Jsonnet code snippet to map the desired claims to the Ory Identity schema.

local claims = {
  email_verified: false,
} + std.extVar('claims');

{
  identity: {
    traits: {
      // Allowing unverified email addresses enables account
      // enumeration attacks,  if the value is used for
      // verification or as a password login identifier.
      //
      // Therefore we only return the email if it (a) exists and (b) is marked verified
      // by Auth0.
      [if 'email' in claims && claims.email_verified then 'email' else null]: claims.email,
      username: claims.nickname,
    },
  },
}

info

Auth0 returns only the sub and sub_legacy claims in the id_token. Ory makes a request to Auth0's /userinfo API and adds the user info to std.extVar('claims').

danger

Don't save secrets such as API keys, credentials, or personal data directly in Jsonnet code snippets. Jsonnet code snippets used for data mapping aren't stored in an encrypted format in The Ory Network.

Encode the Jsonnet snippet with Base64 or host it under an URL accessible to The Ory Network.
```
cat your-data-mapping.jsonnet | base64
```

Download the Ory Identities config from your project and save it to a file:

## List all available projects
ory list projects

## Get config
ory get identity-config {project-id} --format yaml > identity-config.yaml

Add the social sign-in provider configuration to the downloaded config. Add the Jsonnet snippet with mappings as a Base64 string or provide an URL to the file.

              - openid
              - profile

      enabled: true

Update the Ory Identities configuration using the file you worked with:
```
ory update identity-config {project-id} --file updated_config.yaml
```
