Using an external device, such as a smartphone or tablet, can provide a convenient and secure way to share your WiFi password with family members. This approach allows you to create a single, centralized location for storing and distributing your WiFi credentials. By using a device that is always present in the home, you can easily transfer the password to each user's device without having to write it down or rely on others to remember it. Additionally, this method enables you to manage access to your network more effectively, as users will only have access when they are connected to the central hub device. You can use a combination of built-in features like Android Share or AirDrop to share the WiFi password with each user, making it easy to hand off the information. Alternatively, consider using a dedicated family Wi-Fi sharing app, such as Google Family Link or OurHome, which allow you to set up and manage separate profiles for each device, ensuring that everyone has secure access to your network.
