A Service Set Identifier (SSID) is a unique name for a Wi-Fi network. It is used to distinguish your network from others in the area. The SSID facilitates easy network identification for you and your guests and provides additional security against certain threats.
An SSID is primarily used to identify a specific Wi-Fi network. If you connect to a public Wi-Fi network at a coffee shop, you will see the SSIDs of the nearby Wi-Fi networks.
The Main functions of SSIDs include:
- Network Identification: An SSID is essentially the public face of a Wi-Fi network. The network can be identified by its specific name. A network would be largely invisible without an SSID.
- Network Discovery: Wi-Fi networks broadcast their SSIDs to alert devices within the range of their presence.
- Network Differentiation: SSIDs are particularly useful in locations with multiple Wi-Fi networks, such as Walmart Wifi, apartment buildings, or offices. By assigning unique SSIDs to each network, confusion can be avoided, and users can connect to the correct network.
- Network Security: An SSID is used with a password to authenticate and gain access to a network. In general, however, public Wi-Fi and the web require more than a secure access point to maintain safety.
How to Locate an SSID
A sticker attached to your physical router will typically contain your SSID if you have not altered it. You can also view the name of your SSID network by opening the Wi-Fi settings on your computer or smartphone.
