How to open multiple iTerm2 tab with admin privilege
The only way I can think of doing this is by setting up sudo to not require a password.  There are obvious security issues with this, but if those are acceptable in your situation, this is what I would do.

Edit the /etc/sudoers file with the visudo command:

# sudo visudo

Add a line at the bottom which grants the relevant user the ability to run any command as root without being prompted for a password (in this example adam is the user):

adam ALL=(ALL) NOPASSWD: ALL

If you wanted a slightly more secure version, you could restrict them to only being able to run myApp without a password on a particular host (in this example the user is adam, the host is hebe and the only command they can run without a password is /usr/local/bin/myApp):

adam hebe = (root) NOPASSWD: /usr/local/bin/myApp
