In summary, there are two main resources required for a complete auth flow in Flyte:

**An identity layer**
**Identity Layer**

Using an implementation of the `Open ID Connect (OIDC) specification <https://openid.net/specs/openid-connect-core-1_0.html>`__, it enables clients to verify the identity of the end user based on the authentication performed by an Authorization Server. For this flow to work, you must first register Flyte as a new client (app) to the Identity Provider (IdP).
The `OpenID Connect (OIDC) protocol <https://openid.net/specs/openid-connect-core-1_0.html>`__ allows clients (such as Flyte) to confirm the identity of a user, based on authentication done by an Authorization Server. To enable this, you first need to register Flyte as an app (client) with your chosen Identity Provider (IdP).

**An authorization server**

As defined by IETF's `RFC #6749 <https://datatracker.ietf.org/doc/html/rfc6749>`__, the authorization server's role is to issue *access tokens to the client after successfully authenticating the resource owner and obtaining authorization*. In this context, the *resource owner* is the end user of Flyte; and the *client* is the tool or component that intends to interact with ``flyteadmin`` : ``flytepropeller``, ``flyteconsole`` or any of the CLI tools.
As defined by IETF's `RFC #6749 <https://datatracker.ietf.org/doc/html/rfc6749>`__ , the authorization server’s job is to issue access tokens to clients after verifying the user (resource owner) and getting their consent. In this setup:

1. The user of Flyte, is the *resource owner*.

- Sandbox: http://localhost:30081/callback
- Production: https://<your-deployment-URL>/callback
4. Obtain Tenant and Client Information
- After registration, go to the app's Overview page.
- Take note of the Application (client) ID and Directory (tenant) ID—you’ll need these in your Flyte configuration.

5. Create a Client Secret
- From the Certificates & Secrets tab, click + New client secret.
- Add a Description and set an Expiration period (e.g., 6 months or 12 months).
- Click Add and copy the Value of the client secret— it will be used in the helm values.

- Navigate to API Permissions > + Add a permission.
- Select Microsoft Graph > Delegated permissions, and add the following permissions:
``email``
``openid``
``profile``
``offline_access``
``User.Read``

- Go to the Authentication tab, and click + Add a platform.
- Select Mobile and desktop applications.
- Add following URI: ``http://localhost:53593/callback``
- Scroll down to Advanced settings and enable Allow public client flows.
