Authentication & Backends

Netlify CMS stores content in your GitHub repository (GitLab and Bitbucket coming soon!). You'll need to sign in to your GitHub account through the CMS for this to work, and it requires a server. We have a few options for handling this.

Git Gateway with Netlify Identity

Git Gateway another Netlify open source project, together with the Netlify Identity service, provides a way for CMS users to sign in with email and password, and doesn't require them to have a GitHub account. This is a great option for non-technical editors, or if you don't want CMS users to have direct access to your GitHub repo. You can try Git Gateway with Netlify Identity any time via the Test Drive.

Using it in your own project is simple:

  1. Head over to the Netlify Identity docs and follow the steps to get started.

  2. Add the following lines to your config.yml file:

    backend:
      name: git-gateway
      accept_roles: "admin, editor" #optional - accepts all user roles if left out
    
  3. Optionally, you can assign roles to users in your Netlify dashboard, and then only allow certain roles to access the CMS by defining the accept_roles field in the config.yml example above. Otherwise it can be left out.

Git Gateway without Netlify

Git Gateway can be used without Netlify by setting up your own Git Gateway server and connecting it with your own instance of GoTrue (the open source microservice that powers Netlify Identity), or with any other identity service that can issue JSON Web Tokens (JWT).

GitHub Backend

The GitHub backend allows CMS users to log in directly with their GitHub account. Note that the user's GitHub account must have push access to your content repo for this to work.

Because Github requires a server for authentication, Netlify facilitates basic GitHub authentication.

To enable it:

  1. Follow the authentication provider setup steps in the Netlify docs.

  2. Add the following lines to your config.yml file:

    backend:
      name: github
      repo: owner-name/repo-name # Path to your Github repository
    

If you would like to facilitate your own OAuth authentication rather than use Netlify's service, you can use one of the community maintained providers below, and feel free to submit a pull request if you'd like to add yours!

External OAuth Clients:

Author Supported Git hosts Languages Link
@vencax GitHub, GitHub Enterprise Node.js Repo

Check each project's README for instructions on how to configure it.

Bitbucket and GitLab Support

Netlify CMS is meant to be platform agnostic, so were always looking to expand the ecosystem and find new ways to use it. Check out our active PRs in progress for Bitbucket and Gitlab backends.

Git Gateway could also be modified to support these Git hosts. If you're interested, you can file an issue (or a pull request!) in the git-gateway repo.

Options

Both git-gateway and github backends allow some additional optional fields for certain use cases. A full reference is below. Note that these are properties of the backend field, and should be nested under that field.

Field Required Default Description
repo Yes n/a The username of the repo owner, and the repo name, separated by a slash.
branch No master The branch to store published content on.
api_root No https://api.github.com (ignored for git-gateway backend) The API endpoint. Only necessary in certain cases, e.g. for GitHub Enterprise users on the github backend.
site_domain No [location].[hostname] or cms.netlify.com when on localhost Sets the site_id query param sent to the API endpoint. Non-Netlify auth setups will often need to set this for local development to work properly.
base_url No https://api.netlify.com OAuth client URL for the github backend. Required when using an external OAuth server with the github backend.
