A security token is a portable device that authenticates a person's identity electronically by storing some sort of personal information. The owner plugs the security token into a system to grant access to a network service. The Basics of a Security Token Security tokens come in many different forms, including hardware tokens that contain chips, USB tokens that plug into USB ports, and wireless Bluetooth tokens or programmable electronic key fobs, which activate devices remotely for example, to gain access to a car or apartment building.
Password types[ edit ] All tokens contain some secret information that is used to prove identity. There are four different ways in which this information can be used: Asynchronous password token for online banking. Static password token The device contains a password which is physically hidden not visible to the possessorbut which is transmitted for each authentication.
Single sign-on services also use security tokens to log users into third-party websites seamlessly. Disconnected tokens are not linked to the computer or network in any way; rather, the user enters the information from the token manually into the system.
Connected tokens work electronically and automatically transmit information to the network once they're connected.

Key Takeaways Security tokens authenticate identities electronically by storing personal information. They may be used in place of or in addition to a password to prove the owner's identity.
Security tokens are not always secure—they may be lost, stolen, or hacked. Real-World Example of a Security Token You might use a security token to access a sensitive network system such as a bank account, in order to add an extra layer of computer token.
In this instance, the security token is used in addition to a password to prove the account owner's identity. Also, security tokens store data in order to authenticate the owners' identities.
Some store cryptographic keysa system used in cryptocurrency services such as Bitcoin, but the key must be kept secret. Some use time-sensitive passwords, which are coordinated between the token and the network computer token are reset at constant intervals.
Others use biometrics such as fingerprint data to ensure that only the owner computer token the security token can access protected information. Weaknesses of Security Tokens As with any system, security tokens are not flawless.

If internet projects with investment token is lost or stolen or if it isn't in the owner's possession, it cannot be used to access a service. However, the owner can take steps to prevent loss or theft, such as locks or alarms, and the token can be rendered useless to a thief by using two-factor authentication, which requires both an item in the owner's possession for example, a bank card and a piece of knowledge for example, a PIN to access the token.
Security tokens can also be hacked.
This often happens when the owner unknowingly provides sensitive information to an unauthorized provider who then inputs the information into the secure network. This is known as man-in-the-middle fraud.
Any network connected to the Internet is vulnerable to such an attack. Compare Accounts.
