Why does my Google Chrome browser no longer save my password for the PRTG web interface? Is this due to a PRTG change or a Chrome update?
Saving PRTG passwords in Google Chrome browser
As of version 37, the Google Chrome browser does not allow saving login passwords for web pages with invalid certificates. Because the default certificate of PRTG is a self-signed certificate, you will not be able to save your PRTG credentials in Chrome 37 if you have secured the connection to your PRTG web server via SSL.
We recommend that you install a trusted SSL certificate. This avoids the browser warnings when connecting to the PRTG web interface, and you can save your login credentials for PRTG with Chrome 37 as well. For details, see How can I use a trusted SSL certificate with the PRTG web interface?
