Step-by-Step Tutorial#

Public Wi-Fi risk is mostly operational. The right sequence matters more than one-off settings.

Before connecting#

  1. Verify SSID with staff.
  2. Disable auto-join for open networks.
  3. Start VPN before sensitive browsing.
  4. Ensure system and browser are patched.

While connected#

  • avoid banking and admin workflows;
  • enforce HTTPS and respect certificate warnings;
  • keep VPN active for the full session;
  • do not install software from public network context.

Captive portal workflow#

Log in only to activate access, then confirm VPN tunnel status and close the portal tab.

After session#

Forget the network, clear temporary browsing data, review active sessions, and rotate credentials if anything looks suspicious.

Takeaway#

Public Wi-Fi safety is a repeatable routine. Consistency beats improvisation.
