What are 3 ways to authenticate a user?
- Something you know (such as a password)
- Something you have (such as a smart card)
- Something you are (such as a fingerprint or other biometric method)

Message authentication (sometimes called data origin authentication) is the assurance that a given entity was the original source of the received data. Entity authentication (or user authentication) is the assurance that a given entity is involved and currently active in a communication session.
Data authentication is
a critical mechanism to maintain data integrity and nonrepudiation
. Data authentication may be achieved either using conventional encryption algorithms or using public-key cryptography (PKC).
The DBMS authentication feature
removes the need to add an operating system user every time a new user needs to access a database
. A user who is appropriately defined in the database can access the database using a valid Vector user name and password.
Passwords, smart cards, digital certificates, Kerberos, and biometrics
are among the many authentication methods currently employed.
- Something you have e.g. Credit Card, ID Card, etc.
- Something you know e.g. Password, PIN, etc.
- Something you are e.g. Static Biometrics, Fingerprints, etc.
- Something you do e.g. Dynamic Biometrics, Voice, etc.
Biometric Authentication Methods
Biometric authentication relies on the unique biological traits of a user in order to verify their identity. This makes biometrics one of the most secure authentication methods as of today.
- Azure AD.
- Microsoft Account.
- Facebook.
- Google.
- Twitter.
Authentication Schemes
The Form authentication scheme uses a HTML web form for the user to enter their username and password credentials and HTTP Post requests to submit to the server for verification
. It may also be used programmatically va HTTP POST requests.
Web API assumes that authentication happens in the host
. For web-hosting, the host is IIS, which uses HTTP modules for authentication. You can configure your project to use any of the authentication modules built in to IIS or ASP.NET, or write your own HTTP module to perform custom authentication.

The process of providing assurance about the source of information
. Sometimes called identity authentication or origin authentication.
- Password-based authentication. Passwords are the most common methods of authentication. …
- Multi-factor authentication. …
- Certificate-based authentication. …
- Biometric authentication. …
- Token-based authentication.
Authentication with Username and Password
Username and password combination is the most popular authentication mechanism, and it is also known as password authentication. A well-known example is
accessing a user account on a website or a service provider such as Facebook or Gmail
.
