 #### Credentials and Config Options
 
-Use of this plugin can be simplified by using a configuration file containing SafeDNS API credentials, obtained from your MyUKFast [account page](https://my.ukfast.co.uk/applications/index.php). See also the [SafeDNS API](https://developers.ukfast.io/documentation/safedns) documentation.

 The path to this file can be provided interactively or using the `--dns_safedns-credentials` command-line argument. Certbot records the path to this file for use during renewal, but does not store the file's contents.
 
-> **CAUTION:** You should protect these API credentials as you would the password to your MyUKFast account. Users who can read this file can use these credentials to issue arbitrary API calls on your behalf. Users who can cause Certbot to run using these credentials can complete a `dns-01` challenge to acquire new certificates or revoke existing certificates for associated domains, even if those domains aren't being managed by this server.

 Certbot will emit a warning if it detects that the credentials file can be accessed by other users on your system. The warning reads "Unsafe permissions on credentials configuration file", followed by the path to the credentials file. This warning will be emitted each time Certbot uses the credentials file, including for renewal, and cannot be silenced except by addressing the issue (e.g., by using a command like `chmod 600` to restrict access to the file).
