Certificate Information

If you have the CA certificate installed, no trust confirmation dialog will appear, and certificate renewals are handled automatically — no action needed.
If you set up manually without the CA certificate (TOFU), you must delete the Wi-Fi profile and reconnect when the server certificate expires.
※ TOFU (Trust On First Use): on first connection, the user manually inspects and trusts the server certificate.
