Methods of Authentication
System Fundamentals For Cyber Security/Authentication/Methods of Authentication
The ways in which someone may be authenticated fall into three categories, known as the factors of authentication:
- The ownership factor - Something the user has
- The knowledge factor - Something the user knows
- The Inherence factor - Something the user is or does
Each authentication factor covers a range of elements used to authenticate or verify a person's identity prior to being granted access, approving a transaction request, signing a document or other product, granding authority to others, or establishing a chain of authority.
Security research has determined that for a positive authentication, elements from at least two, and preferably all three, factors should be verified.
