 4  This is only helpful for secure cross-device access to **self-hosted** Khoj. You **do not** need this if you're using [Khoj Cloud](https://app.khoj.dev).

 7  [Tailscale](https://tailscale.com) simplifies creating a private VPN using [Wireguard](https://www.wireguard.com/) and OAuth. So you can host and access services on your devices from anywhere.
 8  The instructions below are one way to simply and securely access your self-hosted Khoj from your phone, laptop etc.

10  ### Minimal Setup
11  1. Setup khoj on your preferred machine following the [standard steps](/get-started/setup)
12  2. Sign-up to [Tailscale](https://tailscale.com) and install the app on machines you want to access Khoj from. This usually includes your khoj server, your phone, laptop. Note the tailscale i.p of your khoj server.
13  3. Start khoj on your server by including the flag `--host <your_server_tailscale_ip>`
14  4. Open `http://<your_server_tailscale_ip>:42110` to access khoj from any device on your tailscale network!

17  ### HTTPS Certificate
18  :::info
19  Tailscale uses Wireguard to encrypt and route traffic between your machines. So HTTPS isn't required with Tailscale for secure access. HTTPS with Tailscale is only useful for browsers to not complain about security and block certain features like clipboard access unless HTTPS is enabled.

22  1. Enable [MagicDNS](https://tailscale.com/kb/1081/magicdns#enabling-magicdns) and [HTTPS](https://tailscale.com/kb/1153/enabling-https) toggle on your tailscale admin console [DNS](https://login.tailscale.com/admin/dns) page. Note your unique tailscale domain name (usually ends with .ts.net)
23  2. Create an https certificate for your Khoj server by running the following command:
24     ```bash
25     # Assuming the server is named, `server` and your tailnet is `black-forest.ts.net`
26     # Note path of the .crt and .key files generated
27  
28     tailscale cert server.black-forest.ts.net
29     ```
30  3. Start khoj to be served via https on standard port
31     ```bash
32     sudo KHOJ_DOMAIN=server.black-forest.ts.net \
33     khoj \
34     --sslcert /path/to/your/tailscale.crt \
35     --sslkey path/to/your/tailscale.key \
36     --host=server.black-forest.ts.net \
37     --port 443
38     ```
39  4. You should now be able to access khoj on `https://server.black-forest.ts.net` from any device on your private tailscale network!
