Turning off all password prompts for specific user

Question

I'm looking to turn off all password authentication prompts for a specific user (let's say Steve) on my Ubuntu 21.04 machine.

I added the line steve ALL=(ALL) NOPASSWD: ALL using sudo visudo and that removed the need to authenticate Steve's password when using sudo commands. However, I still get password authentication prompts when using GUI applications such as Ubuntu Software.

Is there a way to turn these prompts off just for Steve? I still want the other accounts to receive the prompts.

Possibly something like this: How do I prevent PolicyKit from asking for a password?. You'd probably want Identity=unix-user:steve rather than Identity=unix-group:admin. Disclaimer - I haven't tried it. — steeldriver, Aug 05 '21 at 11:54
@steeldriver That worked perfectly thanks for the help. Do you want to leave it as an answer so I can mark the question as closed? — Dan, Aug 06 '21 at 06:36
Feel free to add your own answer since you've actually verified it - I was guessing about the details — steeldriver, Aug 06 '21 at 11:49

Thanks to steeldriver's comment and user55572's answer for this answer.

Replace steve with your own user name.

Open a terminal.
Run sudo usermod -aG sudo steve
Run sudo gedit /var/lib/polkit-1/localauthority/50-local.d/disable-passwords.pkla

Add

[Do anything you want]
Identity=unix-user:steve
Action=*
ResultActive=yes

Save the file and close
