Creating a Strong Wi-Fi Password

Creating a unique password for your Wi-Fi network is essential to maintaining a secure connection. Avoid easily guessed passwords or phrases, such as someone’s name, birthdays, phone numbers, or other common information. A strong password should contain a mix of upper and lower case letters, numbers, and symbols. The more complicated your password, the more difficult it is for hackers to break into your network.

Access your router settings. This is usually done by typing the router’s IP address into your web browser.
Log in with your router’s username and password. If you haven’t changed these from the default, they might be something like ‘admin’ and ‘password’.
Navigate to the ‘Wi-Fi settings’ or ‘Wireless security’ section.
Enter your new password. Make sure it meets the criteria for a strong password.
Save your changes and reconnect your devices using the new password.

Managing multiple strong passwords can be challenging. Consider using a password manager to keep track of them. These tools can generate strong passwords for you and store them securely. Some popular options include LastPass, 1Password, and Bitwarden. Using a password manager ensures that you don’t have to remember every complex password, making it easier to maintain a secure network.
