KB40455 - Automatically authorize or re-authorize external protocol request message for Pulse Secure Application Launcher (PSAL) with Google Chrome browser

This article provides step by step instructions how to automatically authorize or re-authorize the Pulse Secure Application Launcher with Google Chrome.

Starting 8.2R1, Pulse Secure implemented Pulse Secure Application Launcher (PSAL) to launch Pulse Secure components.  This application uses a custom URL, pulsesecure://, to deliver and launch client applications.  Due to this fact, Google Chrome will prompt an message to notify end user an application is being launched outside of the Chrome browser.  



For more information about PSAL, please refer to KB40102 - Pulse Secure Application Launcher (PSAL) to deliver & launch Pulse client applications without the use of Activex & Java

When the end user selects the Remember my choice for all links of this type option, the following file will be modified:

• macOS:  ~/Library/Application\ Support/Google/Chrome/Local\ State
• Windows:  C:\Users\<username>\AppData\Local\Google\Chrome\User Data\Local State

protocol_handler":{"excluded_schemes":
{"afp":true,"data":true,"disk":true,"disks":true,
"file":true,"hcp":true,"javascript":true,
"mailto":false,"ms-help":true,"news":false,"nntp":true,
"pulsesecure":false,
...

True = Do not show prompt and block launching PSAL
False = Do not show prompt and continue launching PSAL

To reset the setting to default, delete the "pulsesecure":<value> from the following file. 

Note:  This behavior may change in the future as this is being discussed via the following Chrome ticket:  https://bugs.chromium.org/p/chromium/issues/detail?id=62799
