# 3.3 Generate Debug Certificate

{% hint style="info" %}
You need to generate 2​ signing certificates​ for the google sign-in feature. Debug certificate is required for testing purposes. If you want to test google signing during development, then you should follow the steps. Otherwise, you can ignore it.
{% endhint %}

* To generate a debug certificate, run this command on your terminal from your app

  root directory.

{% tabs %}
{% tab title="Mac" %}

```
keytool -list -v \
-alias androiddebugkey -keystore ~/.android/debug.keystore
```

{% endtab %}

{% tab title="Windows" %}

```
keytool -list -v \
-alias androiddebugkey -keystore %USERPROFILE%\.android\debug.keystore
```

{% endtab %}
{% endtabs %}

{% hint style="info" %}
If this command doesn’t work, then go to this [link](https://developers.google.com/android/guides/client-auth) and copy the debug command from there according to your os.
{% endhint %}

* Use ​**android** as a debug password when the terminal asks for a password.
