Other Auth Providers¶

In addition to Microsoft Entra ID (SSO), xlwings Server supports various authentication providers, including custom ones, which are described here.

Custom authentication¶

Config: To use your own authentication method, activate the custom authentication provider:
```
XLWINGS_AUTH_PROVIDERS=["custom"]
```
Server: To make this work on the backend, you need to implement the validate_token function under app/auth/custom/__init__.py.
Integration: On the frontend, you need to provide the token depending on your integration:
- Office.js add-ins: Adjust globalThis.getAuth under app/static/auth.js so that it returns the token and provider that you will validate with the validate_token function on the backend. For example, to use the custom provider, you’d do:
```
globalThis.getAuth = async function () {
  return {
     token: "...",
     provider: "custom",
  };
};
```
- Other integrations: provide the token via the auth config, see your specific integration for more details: VBA, Google Apps Script, or Office Scripts.
