Note: Kinde Auth is pre-configured as an official provider in Palmr, which means the technical configuration is handled automatically. You only need to provide your OAuth credentials.


Setting up Kinde Auth Application

Creating a Kinde application

To get started with Kinde Auth authentication, you'll need to create an application in your Kinde Dashboard.

  1. Navigate to Kinde Dashboard: Go to your-tenant.kinde.com/admin
Kinde Dashboard
  1. Create new application: Click "Add application" button in the center of the page.

  2. Select application type: Choose "Back-end web" for web-based Palmr instances

  3. Enter application details:

    • Name: Enter a descriptive name like "Palmr File Sharing"
Kinde Application Type Selection
  1. Create application: Click "Save" to generate your Kinde application

Configuring application settings

After creating your application, you'll be redirected to the application page.

Kinde Application Page

Click on the "Details" tab on the sidebar to configure the application settings and get the OAuth credentials.

Kinde Application Details

This is a fake application, you have to use your own.

Getting OAuth credentials

Now you'll get the credentials that Palmr will use to authenticate with Kinde.

  1. Copy Domain: Note your Kinde domain (e.g., your-tenant.kinde.com)

  2. Copy Client ID: The Client ID is displayed in the "Client ID" field

  3. Copy Client Secret: The Client Secret is displayed in the "Client secret" field

Kinde OAuth Credentials

The client ID and client secret shown in the image are examples only (fake credentials). You must use your own credentials from Kinde.

  1. Save credentials: Copy the Domain, Client ID, and Client Secret for later use

Note: For now you only need this configuration, you can come back here later to configure the application as you want.

###Configure application URLs:

You'll need to configure several URLs in your Kinde application settings. Here's what to add for each environment:

Allowed callback URLs

EnvironmentURL
Productionhttps://yourdomain.com/api/auth/providers/kinde/callback
Developmenthttp://localhost:3000/api/auth/providers/kinde/callback
Custom Porthttps://yourdomain.com:5487/api/auth/providers/kinde/callback

Application homepage URI

EnvironmentURL
Productionhttps://yourdomain.com
Developmenthttp://localhost:3000

Developer tip: Kinde Auth authentication works great for modern applications requiring excellent developer experience and scalable authentication infrastructure.


Account linking

By default, if a user is already registered in Palmr with their Kinde Auth email, they will be automatically linked to their Palmr account.

Note: You can't disable account linking. If you want to unlink a user from their Kinde Auth account, you need to delete the user from Palmr.


Technical configuration

Kinde Auth's technical configuration is handled automatically, but understanding the setup can help with troubleshooting:

Provider Type: OAuth 2.0 with OIDC Discovery
Issuer URL: https://your-tenant.kinde.com
Authorization Endpoint: /oauth2/auth
Token Endpoint: /oauth2/token
UserInfo Endpoint: /oauth2/user_profile
Scopes: openid profile email

Field mappings

Palmr automatically maps Kinde Auth user information to local user accounts:

  • User ID: Maps from Kinde's id field
  • Email: Maps from Kinde's preferred_email field
  • Full Name: Maps from Kinde's first_name and last_name fields
  • First Name: Maps from Kinde's first_name field
  • Last Name: Maps from Kinde's last_name field
  • Avatar: Maps from Kinde's picture field
  • Username: Maps from Kinde's preferred_username field

Kinde Auth-specific features

  • Custom Claims: Can include custom user metadata and app metadata
  • Social Logins: Supports integration with various social providers
  • Multi-factor Authentication: Supports Kinde's MFA features
  • Modern APIs: Clean REST APIs and comprehensive SDKs
  • Developer Tools: Excellent documentation and developer experience

Testing the configuration

Verifying the setup

After configuring Kinde Auth authentication, test the integration to ensure everything works correctly.

  1. Check login page: Navigate to your Palmr login page and verify the "Sign in with Kinde" button appears

  2. Test authentication flow: Click the Kinde Auth sign-in button and complete the authentication process

  3. Verify user creation: Confirm that a new user account is created (if auto-registration is enabled)

Login flow verification

The complete authentication process should work as follows:

  1. User clicks "Sign in with Kinde": The browser redirects to Kinde's authorization page
  2. User authenticates: User completes authentication through Kinde (login, MFA, etc.)
  3. Kinde redirects back to Palmr: User returns to Palmr with authentication tokens
  4. Palmr creates or updates user: User account is automatically managed with Kinde information
  5. User accesses Palmr: User is logged in with their Kinde identity

Troubleshooting common issues

Redirect URI mismatch error

Error message: invalid_redirect_uri

Cause: The redirect URI in your request doesn't match what's configured in Kinde application.

Solution:

  1. Check the exact URL in the error message
  2. Add this exact URL to your Kinde application's redirect URIs
  3. Ensure you include the correct protocol (http/https) and port
  4. Remove any trailing slashes unless they're in the callback URL

Access denied error

Error message: access_denied

Cause: User denied permissions or the application isn't properly configured.

Solution:

  1. Verify that your Kinde application requests the correct scopes
  2. Check that users are granting permissions during the authorization flow
  3. Ensure your application is not restricted or disabled
  4. Verify the application has proper permissions set up

Invalid client error

Error message: invalid_client

Cause: Incorrect Client ID, Client Secret, or Domain.

Solution:

  1. Double-check that you've copied the credentials correctly from Kinde
  2. Ensure there are no extra spaces or characters in the credentials
  3. Verify you're using the correct domain format (e.g., your-tenant.kinde.com)
  4. Generate a new Client Secret if necessary

Domain configuration issues

Error message: Domain not found or invalid

Cause: Incorrect Kinde domain or tenant configuration.

Solution:

  1. Verify your Kinde domain is correct (e.g., your-tenant.kinde.com)
  2. Check that your Kinde tenant is active and not suspended
  3. Ensure you're using the correct region for your tenant
  4. Verify DNS resolution for your Kinde domain

Custom claims not available

Cause: Custom claims not properly configured in Kinde.

Solution:

  1. Check Kinde custom claims configuration
  2. Verify that custom claims are included in the ID token
  3. Ensure the claims are properly formatted and accessible
  4. Test with a user that has the expected custom claims

Security best practices

Credential management

  • Never expose secrets: Keep your Client Secret secure and never commit it to version control
  • Rotate credentials regularly: Generate new Client Secrets periodically for enhanced security
  • Use environment variables: Store sensitive configuration in environment variables, not config files
  • Monitor access logs: Regularly review authentication logs for suspicious activity

Scope and permission management

  • Minimal scopes: Only request openid, profile, and email scopes as required by Palmr
  • User consent: Ensure users understand what permissions they're granting
  • Regular audits: Review which users have connected their Kinde Auth accounts
  • Access reviews: Periodically check user access and remove inactive accounts

Production considerations

  • Use HTTPS: Always use HTTPS in production environments
  • Configure proper domains: Use production domains in Kinde application settings
  • Test thoroughly: Verify the complete authentication flow before going live
  • Plan for failures: Have fallback authentication methods available

Next steps

With Kinde Auth authentication configured, you might want to:

  • Configure additional providers: Set up other OIDC providers for more authentication options
  • Customize user management: Fine-tune auto-registration and admin assignment rules
  • Review security settings: Ensure your authentication setup meets your security requirements
  • Monitor usage: Keep track of authentication patterns and user activity
