This question is a bit broad. The device you are referring to is either:
An Authenticator, which generates a unique login, password, or both, for gaining access to a network that is configured in this manner. This is simply called an authenticator. This device is usually a small pocket sized device that does not connect to the computer but has a small display for the information.
A Keylogger, which is a device that captures keystrokes on a computer and is used by computer security teams to log and monitor traffic on certain sensitive systems, and is also used negatively to gather people's login and password information for harmful purposes. This device is generally connected to the computer, between the computer's keyboard cable socket, and the keyboard cable. Keyboard cable > Keylogger > Computer.
Hopefully one of these is what your looking for.

There are many types of authentications can be used in access wireless network. mainly 3 types are used: User only Authentication, Device Only Authentication, User+Device Authentication. They are self explanatory.
Authentication.
Authentication services are used to determine infusers are who they claim to be and are allowed to access what they are trying to access. The purpose of authentication is to protect devices, hosts, and services of a network. Authentication ensures the identity of the entity wanting access. Authentication is the process of determining if a user or identity is who they claim to be. The main goal of authentication is security, authentication is one of the first lines of defense in networking.
No. It does perform authentication, but the password is sent to the server in clear text; this means that anyone with ample knowledge and access to your network or any network between you and the server could grab this information.
core network is for swithiching of calls,routing,authentication,providing services like sms,prepaid,rbt etc but access network is used to provide network access to end users through wireless or wired medium

The correct order for a user attempting to access network resources typically involves the following steps: first, the user initiates a login request, usually by entering credentials. Next, the system authenticates the user's identity against a directory service or authentication protocol. After successful authentication, the user is authorized to access specific resources based on their permissions. Finally, the user can access and utilize the granted network resources.
Bonding in is the process of logging into a system or network, typically requiring authentication to gain access. Bonding out, on the other hand, is the process of logging out or disconnecting from a system or network to end the session and terminate access.
