Creating a Strong Password
Choose a unique password
When it comes to securing your smart home network and devices, one of the first steps you should take is creating a strong and unique password. Avoid using common passwords or ones that are easily guessable, such as your birthdate, pet’s name, or simple patterns like “123456.” Instead, opt for a combination of letters, numbers, and special characters to make your password more complex and harder to crack. The longer and more random your password is, the better.
Use a combination of letters, numbers, and special characters
To make your password even stronger, it is recommended to use a combination of uppercase and lowercase letters, numbers, and special characters. This diversity in characters will make it more challenging for hackers to guess or break your password. Consider using a passphrase rather than a single word, as this can increase the complexity and security of your password.
Avoid using easily guessable information
When creating a strong password, it’s crucial to avoid using easily guessable information that can be easily obtained or deduced. This includes personal information such as your name, address, phone number, or any other easily discoverable details. Hackers can use this information to try and gain access to your network or devices. Remember, the goal is to create a password that is unique and unrelated to your personal life.
Changing Default Device Passwords
