Authentication is an important part of digital system security and ensuring
that only authorised persons have access to sensitive information or
resources.
Let’s take a closer look at each one:-
Three Types of Authentication
Physiological Biometrics
Physiological biometrics is the utilisation of an individual’s unique bodily
traits for authentication purposes. Fingerprints, iris or retina patterns,
facial recognition, voice recognition, DNA are examples of these features.
Biometric authentication systems use physical. characteristics to validate a
person’s identi cation. Because biometrics are di cult to copy or fabricate,
they provide a high degree of security.
However, establishing biometric authentication may be costly and may
necessitate the use of specialised set or so ware.
Password-based Authentication
The most common and frequently used type of authentication is password-
based authentication. To get access to a system or programme, the user
must provide a username or email address as well as a password. The
password should be kept private and should be unique to the user.
Passwords can be enhanced by requiring a minimum length, capital and
lowercase letters, digits, and special characters. Passwords that are weak or
hacked, on the other hand, could pose a substantial security concern.
To improve the security of password-based authentication, it is critical to

2. enforce password restrictions, educate users on secure password practises,
and use multi-factor authentication (MFA).
Token Authentication
Token authentication entails authenticating using physical or virtual tokens.
Tokens can be hardware devices like security tokens or smart cards, or
so ware-based tokens like mobile applications or so ware-based tokens.
These tokens create one-time passwords (OTPs) or security codes that are
updated on a regular basis.
To get access, the user provides the OTP or security code issued by their
token, along with their username or email address, while authenticating.
Because the codes are time-sensitive and unique for each login attempt,
token authentication adds an added degree of protection.
Tokens, on the other hand, can be lost, stolen, or corrupted, thus suitable
measures must be in place to secure them.

Conclusion
These authentication mentioned above provide various degrees of security
and simplicity.
Organizations should carefully evaluate their security requirements and
user needs to choose the appropriate authentication method or a
combination of methods to ensure the right balance between security and
usability.
