User Authentication

Hi, exploring around? I’m Conviner, your call center terminology assistant, ready to help you learn more about contact centers. 

Did you know? Accounts protected by multi-factor authentication (MFA) are 99.9% less likely to be compromised than those using passwords alone.

1. What is User Authentication?

User authentication is the process of verifying a user’s identity before granting access to a system or application. It ensures that only authorized individuals can access sensitive data or perform specific actions.

2. How to authenticate a user?

To authenticate a user, systems typically use one or more verification methods such as:

• Passwords or PINs (something the user knows).
  
  
• Biometric data like fingerprints or facial recognition (something the user is).
  
  
• One-time codes or tokens (something the user has).

3. Why is user authentication important?

User authentication is vital for data security and privacy. It prevents unauthorized access, protects personal and organizational information, and reduces risks of fraud or identity theft in digital systems.

4. What are the 4 means of authentication?

The four common means of authentication are:

1. Knowledge-based – passwords, security questions.
2. Possession-based – security tokens, mobile OTPs.
3. Inherence-based – biometrics like face or voice recognition.
4. Location or behavior-based – IP address, device, or user behavior patterns.
