Authentication Types: What Are They?

by Shaik Rehan

Authentication refers to the process of proving an individual’s identity to gain access to a business’s resources or computer network. The procedure is crucial to preventing unauthorized access, which may result in disastrous data breaches.  

Several authentication options include passwords, one-time codes, and biometrics, ranging from straightforward single-password authentication to intricate multi-factor authentication. 

By using authentication techniques, you may block unauthorized users from accessing your organization’s network and apps while allowing authorized users access. Select the most appropriate authentication technique for your company, which helps to comprehend how each one operates. 

What Is Authentication? 

Authentication ensures a user’s identity is valid before accessing a network or application. Authentication is completed when a user enters credentials that match those previously recorded in the system, confirming the user’s identity and granting access. 

The amount of security required by an organization might not be achieved by only requesting a password or login. For instance, a cybercriminal could be able to break into a network and enter a user’s password to get access. Organizations can employ authentication techniques to let genuine network users in while blocking unauthorized ones. 

What Are the Types of Authentication? 


 1. Token Authentication 

Similar to a smart card with an RFID chip, token authentication is a property-based authentication that employs a specific access token for authenticating a user’s identification. A ticket gives the data required to authenticate the user and provide them appropriate access for the duration of the token’s existence.  

Token authentication requires the user to have a smart card or USB dongle that they can plug into their computer. The card or dongle then requests access by sending a token to the server. After the server has verified the token, it provides users with a new token they keep while utilizing the network. With this technique, the user must log in once rather than multiple times for each program. 

A hacker would require the actual item to obtain access, which is a benefit of this confirmation. Cards should be handled carefully by users to prevent loss. However, token confirmation may be more expensive because devices must be issued to each user. 

2. Passwords

Passwords are the most common form of authentication. Users create a password that only they are aware of and associate it with their username and account on a website or application. The system examines the user’s password in the database to see if it matches the password entered by the user. The system provides the user access if the password is a match. 

 Passwords are widely used and simple to set up. However, they are also ineffective when used as the only authentication technique. According to a recent poll, just 26% of people can remember their passwords without writing them down, while 31% write them down in a notebook. These password storage methods are prone to falls since users may lose or misplace them. 

Many passwords could also be stolen and deciphered with ease. Cybercriminals utilize software to test tens of thousands of password combinations before selecting the best one. The amount and kind of characters used are just two factors that affect how secure a user’s password is. 

3. Behavior Biometrics

Companies that want increased security may utilize behavioral biometric authentication methods. Individuals have distinctive behavioral patterns, such as the speed and force with which they press particular keys when typing, the rate at which they talk, and the length of their walking stride.   

An individual’s unique behavioral patterns can be authenticated by behavior biometrics, such as keystroke dynamics, voiceprints, and gait analysis. 

Behavioral biometric authentication employs artificial intelligence to record how a person interacts with a device like a computer. For instance, each person types differently, pushing and releasing keyboard keys with different frequencies and pressures. Behavioral biometric confirmation aims to match a user’s typing pattern to one stored in the system. 

Behavior biometrics are reliable authenticators since they can never be stolen and are virtually impossible to recreate. The time consumers spend logging in is also decreased by behavior biometrics. Users may believe this technology compromises their privacy, which is a drawback of behavior biometrics. 

4. Multi-Factor Authentication

Most businesses are beginning to accept that multi-factor authentication is necessary for genuinely secure identity management (MFA). MFA calls for two distinct forms of confirmation: a static password and a text message sent to the user’s smartphone. MFA guards against unauthorized users by using something the user is aware of and possesses, such as an email address or smartphone.  

Using time-limited passwords goes hand in hand with MFA. This technique gives the user exclusive access to a password that is only valid for a brief period and becomes useless to steal once that has elapsed. A network can be protected from hackers using any MFA approach. While it is possible to exploit one confirmation factor, doing so with two or more is considerably more difficult. 

One drawback of MFA is that each user must have access to a smartphone, a unique email address, or another form of authentication. If a user misplaces their phone, they might be unable to create a time-sensitive password. 


5. Single Sign-On 

Single sign-on (SSO) is one of the safest authentication methods (SSO). Users may access several apps on a network with SSO by logging in only once for one application and get access to them all without having to do so again. SSO solutions interface with all the websites and apps part of a network to improve the confirmation process. 

When the user enters their credentials in SSO systems, the system uses tokens to confirm their identity. The user is subsequently given access to all network systems and apps through the SSO system. 

By just having to input their credentials once, SSO helps users save time. SSO’s ability to establish and maintain a single password rather than numerous ones for each application is another advantage. However, SSO might raise a company’s security concerns since it gives hackers access to all applications as long as they figure out the user’s single password. 

Which Authentication Method Is the Most Secure?  

Unfortunately, the answer is not that simple. Depending on your business’s size, available security budget, and other unique circumstances, one may be better for you than another. As a starting point, you should enable MFA on all business accounts available if you do not already have any secondary confirmation setup. 


Bottom Line 

Authentication technology is constantly evolving. Businesses need to move beyond passwords and think about authentication to enhance the user experience. Biometric authentication eliminates the need to remember complex and lengthy passwords. Attackers won’t be able to exploit passwords due to improved confirmation techniques and technologies, and a data breach won’t occur.
