Abbreviated as 2FA or TFA
Technical Definition: Simple method of enhancing security, represents an independent channel of authentication
Simple Definition: An extra layer of security to prevent someone from accessing your account
Also called multiple-factor or multiple-step verification
Few people defined it as “An authentication mechanism to double check your identity is legitimate”
After entering your username and password, you will be required to provide another piece of information. This 2nd-factor authentication can be from the following categories:
1] Something you know: A personal identification number (PIN), a password, a specific keystroke pattern or answers to “secret questions”.
2] Something you are: More advanced that might include a biometric pattern of a fingerprint, a voice print, or an iris scan.
3] Something you have: A user having something in their possession like- credit card, a small hardware token or a smartphone
If a user uses 2FA, websites and apps remain more confident about user’s identity, and can even unlock the account.
