Security Token Guide

Have you ever wondered why most of the apps you use tend to ask you for a password, also known as a security token, before you can log in to the app? One of the reasons is that they need to protect your account from a third party who wants to have access to all the activities happening in the app.

The good news is that this article will teach you why two-factor authentication, or having a security token, is necessary to protect your account at all costs and keep it safe from third-party hacking.

Let’s get to it!

What is a Security Token?

A security token is a physical or wireless device that provides two-factor authentication (2FA) for a user to prove their identity during the login process. It serves as a means of identification for both physical access and computer system access.

Whereas a token is a small card that contains security information about a user and can be verified by the system. Security tokens are typically used instead of traditional passwords in most situations.

Security tokens are used to access computer networks, but they can also secure physical access to buildings and act as electronic signatures for documents.

How does a security token work?

I’m sure you will be wondering how this security token really works, yeah?

The security token works in a way that provides you with authentication for accessing a system through any device that generates a password. This could be a USB key, a smart card, or a mobile device.

The device generates a new password for you every time it’s used, so you can use a security token to log in to a computer or virtual private network by typing the password the token generates for you.
Security token technology is based on the use of a device that generates a random number and sends it to a server with user authentication information.

Types of security tokens

Several security token types are used To secure applications and assets.

These include the following:

1. One-time passwords (OTPs): An OTP is valid for only one login session and can’t be used again. After the initial use, the authentication server is notified that the OTP shouldn’t be reused.


2. Disconnected tokens: This is a form of digital security token that doesn’t connect physically or logically to a computer. The device may generate an OTP or other credentials. A desktop application that sends a text message to a cellphone, which the user must input in the login, is using a disconnected token.

3. Connected tokens: A connected token is a physical object that connects directly to a computer or sensor. The device reads the connected token and grants or denies access.


4. Contactless tokens: Contactless tokens form a logical connection with a computer without requiring a physical connection. These tokens connect to the system wirelessly and grant or deny access through that connection. For example, Bluetooth uses a method for establishing a connection with a contactless token.

5. Single sign-on (SSO) software tokens: SSO software tokens store digital information, such as a username or password. They enable people who use multiple computer systems and multiple network services to log in to each system without having to remember multiple usernames and passwords.

Security Tokens Advantage and Vulnerability

A lot of people prefer using passwords and IDs as a form of authentication.

However, security tokens are a more secure option for protecting networks and digital systems. The trouble with passwords and user IDs is that they aren’t always secure.

In addition, passwords are often easy to guess, usually because they are based on easily discoverable personal information.

While security tokens offer a variety of advantages to users and organizations, they can also introduce disadvantages. The main problem with physical security tokens is that they are subject to loss and theft.

A security token, for instance, could disappear or get stolen by someone else. It is necessary to deactivate and replace security tokens that have been misplaced, stolen, or damaged. In the meantime, an unauthorized user in possession of the token may be able to access privileged information and systems. It occurs more with smart cards.
