Custom backend

When integrating FastAuth, you can choose to use a custom backend to handle the authentication and authorization of the user. This is useful if you want to use a different authentication provider or if you want to use a different authorization model.

warning

Implementing a custom backend may require additional development and maintenance, as you will need to implement the authentication and authorization logic for your specific use case.

Aspects to consider​

When implementing a custom backend, there are several aspects to consider:

  • Custom authentication: You will need to implement the authentication logic for your specific use case. This may include implementing a login page, a logout page, and a user profile page. In addition, you will need to implement the logic to verify the user's identity and ensure the transaction or delegated action is authorized.
  • Security: You will need to ensure that no keys or secrets are exposed to the client. This is important to prevent unauthorized access to your resources.
