If your Home Assistant instance is only accessible from your local network you can still protect the communication between your browsers and the frontend with SSL/TLS.
[Let's encrypt]({{site_root}}/blog/2017/09/27/effortless-encryption-with-lets-encrypt-and-duckdns/) will only work if you have a DNS entry and remote access is allowed.
[Let's encrypt]({{site_root}}/blog/2017/09/27/effortless-encryption-with-lets-encrypt-and-duckdns/) will only work if you have a DNS entry and remote access is allowed.
The solution is to use a self-signed certificate. As you most likely don't have a certification authority (CA) your browser will complain about the security. If you have a CA then this will not be an issue.
If you use Chrome browser version 58 or above and/or **don't want to have issues regarding a non-trusted CA or CN (Common Name)**, follow this full tutorial: [Create Root Certificate Authority and self-signed certificate for your Home Assistant. Compatible with Chrome browser > version 58](https://gist.github.com/tiagofreire-pt/4920be8d03a3dfa8201c6afedd00305e). Otherwise, follow this:
To create a certificate locally, you need the [OpenSSL](https://www.openssl.org/) command-line tool.
Change to your Home Assistant [configuration directory](/getting-started/configuration/) like `~/.homeassistant`. This will make it easier to backup your certificate and the key. Run the command shown below.
