# Google credentials

This section contains:

* [OAuth2 single service](/08-0-0-Workflow/integrations/builtin/credentials/google/oauth-single-service.md): Create an OAuth2 credential for a specific service node, such as the Gmail node.
* [OAuth2 generic](/08-0-0-Workflow/integrations/builtin/credentials/google/oauth-generic.md): Create an OAuth2 credential for use with [custom operations](/08-0-0-Workflow/integrations/custom-operations.md).
* [Service Account](/08-0-0-Workflow/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](/08-0-0-Workflow/integrations/builtin/credentials/googleai.md): Get a Google Gemini/Google PaLM API key.


## OAuth2 and Service Account

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.

```

## Compatible nodes

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.

```{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.
