+Configuration for [Technitium](https://technitium.com/).
+
+
+<!--more-->
+
+- Code: `technitium`
+- Since: v4.20.0
+
+
+Here is an example bash command using the Technitium provider:
+
+```bash
+TECHNITIUM_SERVER_BASE_URL="https://localhost:5380" \
+TECHNITIUM_API_TOKEN="xxxxxxxxxxxxxxxxxxxxx" \
+lego --email you@example.com --dns technitium -d '*.example.com' -d example.com run
+```
+
+
+
+
+## Credentials
+
+| Environment Variable Name | Description |
+|-----------------------|-------------|
+| `TECHNITIUM_API_TOKEN` | API token |
+| `TECHNITIUM_SERVER_BASE_URL` | Server base URL |
+
+The environment variable names can be suffixed by `_FILE` to reference a file instead of a value.
+More information [here]({{% ref "dns#configuration-and-credentials" %}}).
+
+
+## Additional Configuration
+
+| Environment Variable Name | Description |
+|--------------------------------|-------------|
+| `TECHNITIUM_HTTP_TIMEOUT` | API request timeout |
+| `TECHNITIUM_POLLING_INTERVAL` | Time between DNS propagation check |
+| `TECHNITIUM_PROPAGATION_TIMEOUT` | Maximum waiting time for DNS propagation |
+| `TECHNITIUM_TTL` | The TTL of the TXT record used for the DNS challenge |
+
+The environment variable names can be suffixed by `_FILE` to reference a file instead of a value.
+More information [here]({{% ref "dns#configuration-and-credentials" %}}).
+
+Technitium DNS Server supports Dynamic Updates (RFC2136) for primary zones,
+so you can also use the [RFC2136 provider](https://go-acme.github.io/lego/dns/rfc2136/index.html).
+
+[RFC2136 provider](https://go-acme.github.io/lego/dns/rfc2136/index.html) is much better compared to the HTTP API option from security perspective.
+Technitium recommends to use it in production over the HTTP API.
