There's a way for change dinamically UserAuth params?

[ulver2812]

Hi, I'm using this library with tzapu/WiFIManager library so I'm collecting the UserAuth params (API_KEY, username, password) and also RealtimeDatabase URL trough the WiFiManager captive portal, this mean that can I have in memory or not the above params.

So if I have in memory the UserAuth params the following code in Setup() function works great:

    // Init Firebase with saved parameters
    UserAuth user_auth(apiKey, username, password);
    initializeApp(aClient, app, getAuth(user_auth), aResult_no_callback);
    authHandler();
    // Binding the FirebaseApp for authentication handler.
    // To unbind, use Database.resetApp();
    app.getApp<RealtimeDatabase>(Database);
    // Set your database URL (requires only for Realtime Database)
    Database.url(dbUrl);
    // In case setting the external async result to the sync task (optional)
    // To unset, use unsetAsyncResult().
    aClient.setAsyncResult(aResult_no_callback);
    ...

but if I'm in the captive portal in order to save my params, after saving, I can't change the UserAuth params in the WiFiManager callbacks "wm.setSaveParamsCallback(saveParamsCallback);" because I can't execute the code above out of the Setup() function.

So my question is: it's possible to change UserAuth params (API_KEY, username, password) and the RealtimeDatabase URL anytime during the sketch execution ? What functions I should use?

Thanks!

All Auth classes can be use locally as the credentials are copied after initializeApp was executed.

If you want to change the authentication method or type, just calling initializeApp with the new Auth class object.

The Realtime database url also can change any time prior to use, which it does not affect with the async tasks that are previously stored or currently run in the async queue.

Please see this custom wrapper class example that the Auth classes are defined locally.
