Setting a Secure Wi-Fi Password

If your Wi-Fi password is cracked, every device on the same network is at risk. You need to set up your router properly.

Use WPA2/WPA3 encryption

For your router's security mode, choose the latest WPA3, or WPA2 if it isn't supported. Older WEP and open networks with no password are easily cracked, so never use them.

A strong Wi-Fi password

A Wi-Fi password follows the same principles as any other password.

  • At least 12 characters, a random string or a passphrase
  • Always change the router's default password and the one printed on the label
  • Change the router admin login password separately as well
  • Don't share it with neighbors, and replace it immediately if it leaks

Separate the guest network

Open a separate guest SSID for visitors. A guest network can't reach your internal devices and files, which protects the main network.

Isolating less-secure IoT (smart-home) devices onto a guest or separate network also reduces the risk.

Regular checkups

Keep managing it periodically even after setup.

  • Update the router firmware to the latest version
  • Turn off the vulnerable WPS feature
  • Occasionally review the list of connected devices and block unfamiliar ones
