Restrict passhash from being used for web login?



I plan to use API calls to pause a sensor when a machine reboots to apply updates. However, I discovered the passhash can be used to access the WebUI, eg: "https://example.com/?username=apiuser&passhash=1234567890".

This is a problem. I can't hide the hash from local admins on those servers, but I don't want them to be able to gain access to the WebUI. I found some posts on this board that indicate the hash should not work for the web interface. Is this a bug?

Thank you for your message.

As mentioned in the second KB article, call based authentication is possible (with passhash) and I'm afraid that there is no option to disable it.

Therefore, I invite you to open a feature request for it by following our guideline here: https://kb.paessler.com/en/topic/79245-how-can-i-propose-new-features-or-sensors-for-prtg

If you have questions, let us know.
