How to set up authentication with SvelteKit and headless WordPress

1. Install WPGraphQL JWT Authentication Plugin:
- Install the WPGraphQL JWT Authentication plugin to enable authentication for your WordPress site[2][5].

2. Configure JWT Authentication:
- Configure the JWT authentication plugin to generate and verify JWT tokens for your WordPress site[2][5].

3. Use JWT Tokens in SvelteKit:
- Use the JWT tokens generated by the WordPress site in your SvelteKit application to authenticate requests to the WordPress GraphQL API[2][5].

4. Implement Authentication in SvelteKit:
- Implement authentication in your SvelteKit application using the JWT tokens. This can be done using a library like NextAuth.js[2][5].

5. Verify JWT Tokens:
- Verify the JWT tokens in your SvelteKit application to ensure they are valid and have not expired[2][5].

6. Handle Authentication Errors:
- Handle authentication errors in your SvelteKit application by displaying an error message or redirecting the user to a login page[2][5].

By following these steps, you can set up authentication with SvelteKit and headless WordPress, ensuring that your application is secure and only accessible to authorized users.
