What is the network security key for hotspots and WiFi on the network device?

There are some points on the computer system related topic of "What is the network security key for hotspots and WiFi on the network device?" following below here:

The diagram shows the network security key and their points are mentioned in the figure and explained below the figure.

• The network security key of wifi and hotspot is a password for protection the mobile devices from other user access

• The doesn't show the password from nearby person who want access the wifi and hotspot connection as the personal mobile

• If the unknown user access the mobile wifi connection can be access the database of the mobile memory storage device

• The mobile devices are used to provide the wifi and hotspot connection to the user with secured and limited user

Let's discuss these points above about the computer system and the mobile wifi and hotspot connection topic of "What is the network security key for hotspots and WiFi on the network device?" explanation following below here:

The network security key of wifi and hotspot is a password for protection the mobile devices from other user access

The network security of wifi and hotspot is a password for protecting the mobile devices from other user access. That means the mobile wifi and hotspot provides the connection to the other mobile user or computer system that has a WiFi device to connect it. The mobile devices wifi and hotspot have a function of security to apply on the wifi network as a security layer to protect the network system to the user who is using and WiFi networks provider. The mobile devices are used to provide and use the wifi and hotspot with secured connection between provider and consumer of the wifi network. 

The network security key on the wifi and hotspot into the mobile devices is a password with different types of security key such as WPA 1, 2, 3 etc. The user has to choose the different types of security layer. If one connection is hacked by the other user, the user can quickly change the security key type.

The mobile wifi hotspot doesn't show the password from nearby person who want to access the wifi and hotspot connection as the personal mobile

The hotspot connection doesn't show the password or security key on the text box of the network security key interface on the mobile device for using the internet service. The internet service is provided by the mobile device through the wifi connection to the other user with the permission of the mobile user who provides the internet service to the user. The hotspot feature does not allow to show the password or security key of the wifi connection to connect the wifi range signal to use the internet service on the mobile or computer system if the computer system installed the wifi device or wifi card into the NIC slot, where the NIC slot is a network interface card or any special wifi card slot on the motherboard of the CPU.

The password or security key or code is necessary to hide from the nearby person who does not see to access the wifi connection because after connecting the wifi it can see the database which is stored into memory of the mobile device as a personal information of the user.

If the unknown user access the mobile wifi connection can be access the database of the mobile memory storage device

If the unknown user accesses the mobile wifi connection can access the database of the mobile memory storage device that means the unknown user can be dangerous for the mobile user who is providing the wifi connection openly to the other user or to the computer system.

If the unknown user accesses the wifi connection then the unknown user can steal the database and information about the person or user of the mobile from the access of the memory of the mobile device. The unknown also steals the information and database file that contains valuable content and information for profit of the user. It also can see the code of payment application software or spread viruses or malicious files into the mobile devices memory to access and control the mobile devices. These types of user who accesses the mobile device and controls through the virus or malicious files can steal the money from the payment application software.

The mobile devices are used to provide the wifi and hotspot connection to the user with secured and limited user

The mobile devices are used to provide the wifi and hotspot connection to the user with secured and limited user, that means the secured and limited user is known as the permission allowed by the user who provides the wifi and hotspot connection through the mobile device. The secured connection is protected by the network security key and limited in the wifi network means the user can access the wifi connection when the mobile user gives the permission to the user who wants to connect the mobile wifi connection to the other user.

The wifi connection is protected when the user applies the network security key on the mobile wifi setting to change the open types of network to wifi protected access from the network security key with different versions WPA1,2,3…, etc.

It is also necessary to apply because it reduces the user traffic of using the internet service loads through the mobile connection.
