Hey Rakesh,
What version of Qlik Sense are you running?
Broadly speaking the service account password, in a clean system, are embedded in:
Pre-June 2017:
June 2017+
- Windows Services Applet
- monitor_apps_* data connections
Other optional places where there are stored password inside of Qlik Sense include:
- Other data connections
- User Directory Connectors
Other places where the password can be stored in Windows include, but are not limited to:
- Windows Vault
- DSN created in the ODBC panel
In a June 2017+ system, assuming you have Qlik CLI, then this script is useful: https://github.com/levi-turner/QlikSenseScripts/blob/master/qlik_sense_pwd_change.ps1 (note there still is a logic bug which I will need to get around to where the QRS can be non-responsive to the API calls; the delay seems to resolve things)
