Authentication is nothing but the validation of user’s identitybefore giving them access to the system.
There are multiple ways of authenticating a particular user:
- Two factor authentication: This methodrequires that the user has to enter a second authentication factorin addition to password. This additional authentication factorcould be based on security question or captcha.
- One time password: A one time password is anautomatically generated numerical or alphanumerical string whichauthernticates users.
