Entering the correct login information lets the website know 1) who you are and 2) that it is actually you accessing the website.
What are the types of authentication?
The most common authentication methods are Password Authentication Protocol (PAP), Authentication Token, Symmetric-Key Authentication, and Biometric Authentication. And that covers a whole host of different authentication methods and use cases that are being tackled all over the world.
What is the most commonly used form of authentication?
Password – The use of a user name and password provides the most common form of authentication. You enter your name and password when prompted by the computer. It checks the pair against a secure file to confirm.

A good example of two-factor authentication is the withdrawing of money from an ATM; only the correct combination of a bank card (something the user possesses) and a PIN (something the user knows) allows the transaction to be carried out.
What are the three independent authentication factors?
Three-factor authentication (3FA) is the use of identity-confirming credentials from three separate categories of authentication factors – typically, the knowledge, possession and inherence categories. Multifactor authentication dramatically improves security.
What are main authentication protocols?
LDAP, Kerberos, OAuth2, SAML, and RADIUS are all useful for different authorization and authentication purposes and are often used with SSO. The protocol you choose should reflect your application needs and what existing infrastructure is in place.
