If the mere mention of an SSID confuses you, read on as we dive into SSIDs and explore why they’re a key element of any Wi-Fi network.

What is an SSID?
An SSID (Service Set Identifier) is the unique name of your Wi-Fi network that’s visible when you search for available networks on your device. It’s basically a label that identifies a network, letting you connect to the right Wi-Fi hotspot when multiple ones are within range.
SSIDs can be up to 32 characters long and made up of letters, numbers, and special characters. These IDs themselves don’t provide any security — routers just broadcast them so nearby devices can find and display available networks for people to recognize and connect to.
Your router brand plays some part in the name your SSID displays. Many branded wireless routers come with a default SSID, but these can be easily changed to avoid confusion from similar names.
This is where your creativity comes into play. Your new SSID could range from the hilarious “Never Gonna Give You Wi-Fi” to infinitely pranky liners like “404 Network Unavailable” and clever names like “Tell My Wi-Fi Love Her.”
Sidenote: Remember that your SSID name remains a public affair.
Functions of an SSID
An SSID’s sole function is to tell Wi-Fi networks apart.
Typically, an SSID (Service Set Identifier) pops up on your screen when your mobile device is already connected to a wireless network.
A common scenario, just as I’ve painted above, is where an individual takes their mobile device to a nearby coffee shop and tries to connect to the local Wi-Fi network.
A long list of SSIDs usually follows for you to cherry-pick from. So, when you see and connect to your favorite coffee shop’s Wi-Fi – the SSID has served its function.
