Only the superuser can manage services through the systemctl. There is no way to remove this behavior, just workarounds.
The safest option: allow the superuser to execute the command without a password and use `sudo systemctl start myservice`
To do this, enter `sudo visudo` find the line `%admin ALL=(ALL) ALL` and add after it: `%admin ALL=NOPASSWD: /usr/bin/systemctl` Save the file (by default `Ctrl+o` then `Enter` then `Ctrl+x`) Now you can use the command `sudo systemctl start myservice` without password.
