> For the next step, you need to generate two hash ids. To do that, run the following commands on the terminal.

1. Scroll down on the right pane until you reach ‘Add a product’, select Facebook Login&#x20;
2. You will be redirected to the quick start page.
3. Select Android. Skip 1 & 2.

{% tab title="Mac" %}

```
keytool -exportcert -alias androiddebugkey -keystore ~/.android/debug.keystore | openssl sha1 -binary | openssl base64
```

{% endtab %}

{% tab title="WIndows" %}

```
keytool -exportcert -alias androiddebugkey -keystore "C:\Users\USERNAME\.android\debug.keystore" | "PATH_TO_OPENSSL_LIBRARY\bin\openssl" sha1 -binary | "PATH_TO_OPENSSL_LIBRARY\bin\openssl" base64
```

{% endtab %}
{% endtabs %}

1. Use ​**android**​ as a debug password. After that, you will get a hash ID like this.

1. For the release hash ID, run the following command by replacing your alias key name and Keystore location. You can get these from your a​ndroid/key.properties ​file.

```
keytool -exportcert -alias YOUR_RELEASE_KEY_ALIAS -keystore YOUR_RELEASE_KEY_PATH | openssl sha1 -binary | openssl base64
```

1. After that, you will get another **hash ID**. Now, copy and paste them into the next steps of the Facebook developer site. Like this,

4. Now go to ​**android/app/src/main/res/values/strings.xml** file​ and change the **facebook\_app\_id** and **facebook\_client\_token**.
