Setting your encryption mode to **Off (not recommended)** redirects any HTTPS request to plaintext HTTP.

        accDescr: With an encryption mode of Off, your application does not encrypt traffic between the visitor and Cloudflare or between Cloudflare and your server.
        A[Browser] <--Unencrypted--> B((Cloudflare))<--Unencrypted--> C[(Origin server)]
```

## Use when

Cloudflare does not recommend setting your encryption mode to **Off**.

## Required setup

* Dashboard

  To change your encryption mode in the dashboard:

  1. Log in to the [Cloudflare dashboard](https://dash.cloudflare.com) and select your account and domain.
  2. Go to **SSL/TLS**.
  3. Choose an encryption mode.

* API

  To adjust your encryption mode with the API, send a [`PATCH`](https://developers.cloudflare.com/api/resources/zones/subresources/settings/methods/edit/) request with `ssl` as the setting name in the URI path, and the `value` parameter set to your desired setting (`off`, `flexible`, `full`, `strict`, or `origin_pull`).

## Limitations

When you set your encryption mode to **Off**, your application:

* Leaves your visitors and your application [vulnerable to attacks](https://www.cloudflare.com/learning/ssl/why-use-https/).
* Will be marked as "not secure" by Chrome and other browsers, reducing visitor trust.
* Will be penalized in [SEO rankings](https://webmasters.googleblog.com/2014/08/https-as-ranking-signal.html).

### Incompatible settings

When you set your SSL/TLS encryption mode to **Off**, you will not see the options for [**Always Use HTTPS**](https://developers.cloudflare.com/ssl/edge-certificates/additional-options/always-use-https/) or [**Onion Routing**](https://developers.cloudflare.com/network/onion-routing/).

[Authenticated Origin Pull](https://developers.cloudflare.com/ssl/origin-configuration/authenticated-origin-pull/) does not work when your [**SSL/TLS encryption mode**](https://developers.cloudflare.com/ssl/origin-configuration/ssl-modes/) is set to **Off** or **Flexible**.
