nmcli-agent

nmcli agent command

nmcli agent runs nmcli as an agent daemon that responds to NetworkManager's requests for secrets (passwords, keys) or polkit authorization requests. This is useful in environments without a desktop secret agent or polkit agent.As a secret agent, nmcli can provide Wi-Fi passwords, VPN credentials, and other secrets when NetworkManager needs them to establish connections. It prompts the user in the terminal for required credentials.As a polkit agent, nmcli handles authorization prompts for privileged NetworkManager operations, allowing command-line authentication without a graphical polkit agent.
