What is Cloudflare Access

Cloudflare Access is a secure, cloud-based zero-trust solution for managing and authenticating user access to internal applications and resources.

Preparation

The following placeholders are used in this guide:

• company.cloudflareaccess.com is the FQDN of your Cloudflare Access subdomain.
• authentik.company is the FQDN of the authentik installation.

To proceed, you need to register for a free Cloudflare Access account and have both a Cloudflare account and a publicly accessible authentik instance with a trusted SSL certificate.

:::note This documentation lists only the settings that you need to change from their default values. Be aware that any changes other than those explicitly mentioned in this guide could cause issues accessing your application. :::
