The `LINODE_API_KEY` will be saved in `~/.acme.sh/account.conf` and will be reused when needed.
## 15. Use FreeDNS
FreeDNS (https://freedns.afraid.org/) does not provide an API to update DNS records (other than IPv4 and IPv6
dynamic DNS addresses). The acme.sh plugin therefore retrieves and updates domain TXT records by logging
into the FreeDNS website to read the HTML and posting updates as HTTP. The plugin needs to know your
userid and password for the FreeDNS website.
```sh
export FREEDNS_User="..."
export FREEDNS_Password="..."
```
You need only provide this the first time you run the acme.sh client with FreeDNS validation and then again
whenever you change your password at the FreeDNS site. The acme.sh FreeDNS plugin does not store your userid
or password but rather saves an authentication token returned by FreeDNS in `~/.acme.sh/account.conf` and
reuses that when needed.
Now you can issue a certificate.
```sh
acme.sh --issue --dns dns_freedns -d example.com -d www.example.com
```
Note that you cannot use acme.sh automatic DNS validation for FreeDNS public domains or for a subdomain that
you create under a FreeDNS public domain. You must own the top level domain in order to automaitcally
validate with acme.sh at FreeDNS.
# Use custom API
If your API is not supported yet, you can write your own DNS API.
