Since Big Sur, it inserts the password into the "Account Name" field (probably because the focus is on that field by default). Any idea how to resolve that?

Same issue as @GamerGun . I recommend the adjustment of the enterPassword() like this:

enterPassword() {
  sleep 1
  osascript -e "tell application \"System Events\" to keystroke tab"
  osascript -e "tell application \"System Events\" to keystroke \"${1}\""
  osascript -e "tell application \"System Events\" to keystroke return"

 # optional.  Only relevant if your VPN is displaying a welcome banner.
  sleep 1
  osascript -e "tell application \"System Events\" to keystroke return"
}
