This article applies to PRTG Network Monitor 13.2.3 through 17.3.33

Customizing Login Screen: Removing the Forgot Password Link

Important note: The current customization approach is unsupported and deprecated as of versions 17.3.34/17.4.35. This customization no longer works. For more details, see How can I re-brand and customize the PRTG web interface using CSS and Javascript?

The preferred solution is to offer a customized login screen to your users, see: How do I customize the PRTG web interface's login screen?

The second best solution is to remove the <a href="/public/forgotpassword.htm">...</a> code from the HTML templates

As of PRTG 13.2.3 or later, find these three files and remove the <a> link from the html.

  1. index.htm in the folder "PRTG Newtork Monitor\webroot\"
  2. index.htm in the folder "PRTG Network Monitor\webroot\m\" (this path is deprecated as of PRTG version 16.3.26)
  3. login.htm in the folder "PRTG Network Monitor\webroot\public"

The HTML code must be removed from <a...> to </a>, including the translation placeholder:

<a class="nohjax" href="/public/forgotpassword.htm"><#lang key="html.index.htm.Forgotyourpassword1" default="Forgot password?"></a>

Afterwards I'd recommend making the file read only, otherwise it will be overwritten when you install an update of PRTG. But this also make it impossible for the installer to update these files in case we release new versions. So use this tip with care.


For more information see the instructions on How to Re-Brand and Customize the PRTG Web Interface Using CSS.

I have three files that reference the forgotten password line:

  • login.htm
  • loginform.htm
  • index.htm

I have removed the <a> link from all three files (I even tried to change some of the text in these files), saved the files, but the login page does not change. I've restarted the PRTG server and gone to the login page from another browser/computer just to make sure that the page wasn't cached, but I can't get this to change/update. Any ideas?

@stonetear: I have updated the answer above. Your changes should suffice. Please make sure your web browser reloads the page (Shift/CTRL-F5) and that the web browser looks at exactly the PRTG installation that you changed the files for.

Yes, that's what I'm saying. Even after changing all three of those files, restarting PRTG, and trying from several different browsers, the link remains. I've removed the entire line from <a> to </a> for the line that references the forgotten password text and link. Very puzzled here!

Please make sure you actually edited the files at the right location and clear your browser cache.

I have done so.

I have also tried editing some basic text in welcome.htm (simply adding or removing words), saving the file, restarting PRTG, trying from multiple computers, and the text does not change. It's almost like PRTG is caching a copy itself somehow, or drawing the text from an alternate 'original' copy of the file.

I'm not sure what I could be missing, it's very straight forward. Edit htm file, restart PRTG server service, try to load page from three different PCs, making sure that the caches are cleared.

I know this works for some files, because I have successfully modified many of the other files (including CSS files), but some values/website files refuse to display updated text no matter how many times I edit them, restart the server, or refresh my browsers.

When editing HTML file of PRTG you must make sure that you do not edit text inside the <#LANG> placeholders, e.g.

<#lang key="html.welcome.box4a" default="Download the Windows GUI">

If you change this text you are only changing the internal default value of the string inside the translation system. No change will be visible on the site, because the string which is used by the web server is taken from the selected language file, not the HTM template file. So you should remove the <#lang ...> placeholder and replace it with your own text.

Note 1: If you edit file of PRTG your changes will be overwritten by the installer the next time you install an update!

Note 2: A restart of the server service is not required when you change the htm files. PRTG does not cache the files itself (it relies on the OS' file cache)

Another option is to leave pages mentioned above intact and change the functionality of the forgotpassword.htm page.

Locate the \webroot\public\forgotpassword.htm file, remove all content (after having made a safety copy first) and paste the code from below:

<html lang="en-US">
        <meta charset="UTF-8">
        <meta http-equiv="refresh" content="1;url=login.html">
        <script type="text/javascript">
            window.location.href = "login.html"
        <title>Page Redirection</title>
         If you are not redirected automatically, follow the <a href='login.html'>link to login page</a>

As a result, the user is linked back to the login page when he clicks the 'forgot password' link.

This way, all pages mentioned above can remain unchanged and updates of PRTG will automatically include possible new login pages, not requiring you to repeat any steps.

The new forgotpassword.htm file will need to be flagged as read-only
