Multi-factor Authentication (MFA)
Multi-factor Authentication (MFA) is the use of multiple factors to confirm the identity of someone who is requesting access to an application, website, or other resources. Multi-factor authentication is the difference between, for example, entering a password to gain access and entering a password plus a one-time password (OTP), or a password plus answering a security question.
By requiring people to confirm identity in more than one way, multi-factor authentication provides greater assurance that they really are who they claim to be, which reduces the risk of unauthorized access to sensitive data. After all, it is one thing to enter a stolen password to gain access, and another to enter a stolen password and then enter an OTP that was texted to the legitimate user’s phone.
The following are categories of multifactor authentication methods:
Selecting categories should be according to the required access and based on user types and locations. This will affect the success of the service you are looking to secure, and here is TSC’s secret in gaining the trust of their clients.
