# Google

This section contains:

* [OAuth2 single service](/integrations/builtin/credentials/google/oauth-single-service.md): Create an OAuth2 credential for a specific service node, such as the Gmail node. Two options exist:
  * [Managed OAuth2](/integrations/builtin/credentials/google/oauth-single-service.md#managed-oauth2): Sign in with Google directly on n8n, with no setup required on the Google Cloud Console. Available for n8n Cloud users only, for certain Google nodes.
  * [Custom OAuth2](/integrations/builtin/credentials/google/oauth-single-service.md#custom-oauth2): Configure an OAuth2 app in the Google Cloud Console and connect it to your n8n credential.
* [OAuth2 API (generic)](/integrations/builtin/credentials/google/oauth-generic.md): Create an OAuth2 credential for use with [custom operations](/integrations/builtin/custom-api-actions-for-existing-nodes.md).
* [Service Account](/integrations/builtin/credentials/google/service-account.md): Create a [Service Account](https://cloud.google.com/iam/docs/service-account-overview) credential for some specific service nodes.
* [Google PaLM and Gemini](/integrations/builtin/credentials/googleai.md): Get a Google Gemini/Google PaLM API key.

## OAuth2 and Service Account <a href="#oauth2-and-service-account" id="oauth2-and-service-account"></a>

There are two authentication methods available for Google services nodes:

* [OAuth2](https://developers.google.com/identity/protocols/oauth2): Recommended because it's more widely available and easier to set up.
* [Service Account](https://cloud.google.com/iam/docs/understanding-service-accounts): Refer to the [Google documentation: Understanding service accounts](https://cloud.google.com/iam/docs/understanding-service-accounts) for guidance on when you need a service account.

### Managed OAuth2 for n8n Cloud users <a href="#managed-oauth2-for-n8n-cloud-users" id="managed-oauth2-for-n8n-cloud-users"></a>

[Managed OAuth2](/integrations/builtin/credentials/google/oauth-single-service.md#managed-oauth2) is available for the following Google nodes, for n8n Cloud users. This provides a simplified credential creation process:

## Compatible nodes <a href="#compatible-nodes" id="compatible-nodes"></a>

Once configured, you can use your credentials to authenticate the following nodes. Most nodes are compatible with OAuth2 authentication. Support for Service Account authentication is limited.

{% hint style="warning" %}
**Gmail and Service Accounts**

Google technically supports Service Accounts for use with Gmail, but it requires enabling domain-wide delegation, which Google discourages, and its behavior can be inconsistent.

n8n recommends using OAuth2 with the Gmail node.
