Auth0

Ory Console

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

1. Sign in to Ory Console and select Social Sign-in.

2. Click the switch next to the Auth0 logo to start the configuration.

3. Copy the Redirect URI and save it for later use.

4. Create an Auth0 Application for your Auth0 Tenant, noting the following points:

   • Choose the application type to be Regular Web Applications.
   • Paste the saved Redirect URI from Ory into the Allowed Callback URLs field in the Settings tab of the registered application.

5. Go to the Settings tab of the registered application on the Auth0 dashboard and copy the following data to the corresponding fields in the form in the Ory Console:

   • Client ID
   • Client Secret

6. Go to the Advanced Settings then Endpoints and copy the Auth0 top-level domain (typically https://myAuth0Tenant.auth0.com) to the Tenant URL field of the form in the Ory Console.

7. In the Scopes field of the form in the Ory Console, add the following scopes:

   • openid
   • profile
   • email

8. In the Data Mapping field of the form in the Ory Console, add the following Jsonnet code snippet, which maps 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').

   <JsonnetWarning format="Jsonnet code snippets" use="data mapping" />

9. Click Save Configuration.

Ory CLI

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

1. Create an Auth0 Application for your Auth0 Tenant.

2. In the created app, set the redirect URI to:

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

3. 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').

   <JsonnetWarning format="Jsonnet code snippets" use="data mapping" />

4. Encode the Jsonnet snippet with Base64 or host it under an URL accessible to Ory Network.

   cat your-data-mapping.jsonnet | base64

5. 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

6. 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.

   selfservice:
     methods:
       oidc:
         config:
           providers:
             - client_id: .... # Replace this with the OAuth2 Client ID provided by Auth0
               client_secret: .... # Replace this with the OAuth2 Client Secret provided by Auth0
               id: auth0 # this is `<provider-id>` in the Authorization callback URL. DO NOT CHANGE IT ONCE SET!
               mapper_url: "base64://{YOUR_BASE64_ENCODED_JSONNET_HERE}"
               # Alternatively, use an URL:
               # mapper_url: https://storage.googleapis.com/abc-cde-prd/9cac9717f007808bf17f22ce7f4295c739604b183f05ac4afb4
               issuer_url: .... # Replace this with the endpoint of the Auth0 tenant.
               provider: auth0
               scope:
                 - openid
                 - profile
                 - email
         enabled: true

7. Update the Ory Identities configuration using the file you worked with:

   ory update identity-config {project-id} --file identity-config.yaml

Troubleshooting

When you add a social sign-in provider, you can encounter common problems such as:

• Redirect URI mismatch
• Redirect loops during registration
• Domain verification issues

To troubleshoot those issues, read Social sign-in troubleshooting.

Requested url does not match any rules

If you see this error after clicking on "Sign in with Auth0", make sure that the "Tenant URL"/issuer_url is set correctly.
