- Verify Your Identity: You’ll be prompted to verify your identity through your phone number or email to confirm you have access to the secondary verification method.
- Save Recovery Codes: Most services provide recovery codes in case you lose access to your secondary authentication method. Save these codes somewhere safe.
- Regularly Update Your Settings: Check your MFA settings periodically to ensure they are up to date, especially if you change your email or phone number.
Securing Home Networks
Setting Up Guest Networks
Setting up a guest network for your smart devices is a helpful measure in reducing the risk of a breach affecting your vital data. A guest network isolates your smart devices from your main network. Here’s how you can do it on most modern routers:
- Access Router Settings: Access the router settings by entering your router’s IP address in a web browser’s address bar. It is usually “192.168.1.1” or “192.168.0.1,” but you can check your router’s manual or the router itself for the correct IP address.
- Log in to the Router: Enter your router’s username and password. If you haven’t already changed it, the default username and password are often both “admin.” If not, check your manual or the device.
- Navigate to Guest Network Settings: Once logged in, look for the “Guest Network” option, commonly found under the wireless settings or advanced settings menu.
- Enable the Guest Network: Enable the guest network option to create a separate network for your smart devices.
- Set Up Network Name (SSID): Name the new network something like “HomeGuest” or “IoTDevices.”
- Configure Security Settings: Set a strong password for your guest network that includes lowercase and uppercase characters, special characters, and numbers. Choose WPA3 if available; if not, select WPA2 to meet minimum security standards.
- Restrict Guest Network Access: To isolate the devices on your guest network from the main network, configure the guest network’s settings by enabling “AP Isolation” or a similar option.
- Save and Reboot: Save the settings and reboot the router to apply the changes.
- Connect Devices to Guest Network: Connect your smart devices to the newly created guest network. This way, any breach in the guest network is contained, ensuring your main network stays safe.
