## How to change Google Login Details?

#### Creating an Android Project

* Open Android Studio (Here I am using Android Studio 3.0). And you need to create a project with an **Empty Activity**. I created a project named GoogleLoginExample.
* Once your project is loaded then click on **Tools->firebase**&#x20;

![Google Login Android](https://cdn.shortpixel.ai/client/to_avif,q_glossy,ret_img,w_187,h_180/https://www.simplifiedcoding.net/wp-content/uploads/2015/11/Google-Login-Android.png)

* Now you need to connect to firebase. It will again open a window, and from this window, you can create a new Firebase Project, or if you want you can also choose an existing one.

![Connecting to Firebase](https://cdn.shortpixel.ai/client/to_avif,q_glossy,ret_img,w_436,h_273/https://www.simplifiedcoding.net/wp-content/uploads/2015/11/Connecting-to-Firebase.png)

* After connecting to Firebase, click on Add Authentication and accept the changes. It will add all the required dependencies.

#### Enabling Google Login in Firebase Console

* If we want to use Google Login with Firebase, then we also need to enable it in the Firebase Console (Default disables it).
* To enable it, go to Firebase Console **(console.firebase.google.com).** Then from the right, select Authentication, then select **SIGN-IN METHOD**, and here you need to allow Google Option. (See the image below it is disabled, and you need to enable it).
