 You can save the file as anything you like and anywhere you’d like as long as you inform the script of its location using the `--credentials` parameter. By default, the script will look for a file named *cloudflare.credentials* in the same path as the script.
 
+Please remember that this file basically contains a password! As a result, it should be protected and access limited to the root account:
+
+```bash
+chown root:root /path/to/cloudflare.credentials
+chmod 600 /path/to/cloudflare.credentials
+```
+
 ### Bearer token
 
 I chose to use an API bearer token instead of a username/password or Global API token for security reasons. Your username/password and Global API token provide unfettered access to your account so if anyone gets hold of them, they can do anything to your account. An API bearer token, by contrast, can only do what you authorize it to do and you can revoke it at any time. Therefore, I suggest making a bearer token that is based on the “Edit zone DNS” template and restricted to the specific domain/zone you wish to update. Cloudflare provides an [excellent article](https://support.cloudflare.com/hc/en-us/articles/200167836-Managing-API-Tokens-and-Keys) on how to generate this token.

 minutes) after everything is working.

 It is NOT necessary to enable/start the *cfddns.service*, only the timer needs to be active.

 ## Logging
 
 The script logs every major action it takes and provides details on any errors it encounters in the log file (see the [parameters section](#parameters) for details about setting log location and name).  If errors are encountered, they are colour coded red and an explanation of the error code is provided.

 This is basically a modified version of the '*applyeurodate*' script that comes with Logwatch.  It had to be modified to search within [square brackets] and to accept characters coming before the stamp (i.e. ANSI colour codes).  If you change the '**stamp**' variable in the updater script to update the timestamp to your liking (which to totally fine!) then you'll probably have to update this file.  There are two lines you need to modify to suit your new '**stamp**' variable.
