The only type of installer where the password can be included is the Agent installer script.
This solution only works for ESET Management Agent for Windows.

To create an installer that can override a password-protected agent, you have to create a new (or modify existing) Live installer script:

Create Agent script Installer, but do not deploy it on a computer yet.
Extract the downloaded file PROTECTAgentinstaller.zip.
Open the PROTECTAgentinstaller.bat in a simple text editor like Notepad.
Find the section between lines 30 and 46 where the parameters shown below are selected.

Figure 1-1
Add a line between lines 36 and 37 as seen in the image below:
```
echo.PASSWORD=secret_123 >> "%installConfigFile%"
```
Substitute the example password secret_123 with the password of your existing ESET Management Agent.

Save the changes in the file.
Use this modified installer for the ESET Management Agent re-installation according to step 4 in the ESET PROTECT On-Prem section or step 5 in the ESET PROTECT section of this article.
