First, the use is different.

1. Network security key: used to encrypt and transmit data on the network and verify secure access.

2.wifi password: used to prevent unauthorized users from accessing the wireless network.

Second, the characteristics are different.

1, network security key: public key encryption technology uses asymmetric keys for encryption and decryption. Each pair of keys contains a public key and a private key. The public key is public and widely distributed, while the private key is never public, only you know it.

2.wifi password: It can be a simple password or a combination of numbers and letters generated by yourself. It can be an easy-to-remember phrase, word or combination of numbers. There are many types of wireless security scheme configurations when configuring a wireless network.

Wi-Fi (pronounced as /wafa/, pronounced as /wifi/ in French), also known as "action hotspot" in Chinese, is a trademark of the manufacturer of the Wi-Fi alliance as a product brand certification, and is a wireless LAN technology created in the IEEE802. 1 1 standard.

Based on the close relationship between the two systems, Wi-Fi is often regarded as synonymous with IEEE 802. 1 1 standard. "Wi-Fi" is often written as "Wifi" or "WiFi", but they are not recognized by the Wi-Fi alliance.

Not every product that conforms to IEEE 802. 1 1 has applied for the certification of the Wi-Fi Alliance, and the relative lack of Wi-Fi certification does not necessarily mean that it is incompatible with Wi-Fi devices.
