What is a certificate based authentication?

When to use, Why, How it works? and What are the advantages of using certificate based authentication? Certificate based authentication is considered as one of the most secure authentications. We can make our web-app/websites secured with just 3 simple steps which are- Letting web browsers use SSL (HTTPS) for communication between them and us Application servers Application. The communication between application server and browser is usually in text mode HTTP 1.1 and HTTP 1.0

The below are the basic ways to protect the website from the unauthorized users. Letting web browsers use SSL (HTTPS) for communication between them and us, Application servers Application.0 The communication between client (web browser) and application server using SSL/TLS is in encrypted mode and it may be in both text and binary mode. This feature works with https:// . What do we mean by "encrypted mode"? Encrypted mode means the data is encrypted and encrypted mode can be in both text and binary mode. In encrypted mode the messages transmitted to and from internet are not only protected from the unauthorized access but also it can't be read by anyone. The SSL/TLS connection uses a digital certificate that binds the public key of the server to a certificate subject name. Digital certificates work best when both server and client have a trusted source of the same version of the certificate. A trusted source may be a software repository or the trusted root certificate authority and also a list of trusted partners that issue certificates for websites. These sources help protect the certificates and prevent attackers from falsely impersonating a trusted site. SSL/TLS connections use digital certificates to create a trust chain which is used to verify the identity of the server. For client authentication, browsers generally use the certificate issued for the server, if it is available. Also if the browser supports it, it allows the browser to ignore the server certificate if the trust chain does not meet certain requirements.

The process for SSL/TLS certificate based authentication is described in the following figure. Here it can be seen that it takes three simple steps to let the Browser send and receive the secured connection.

If you have no idea about it? Let's understand it by taking example of a basic website like Facebook.

What is the difference between token authentication and session authentication?

I want to use token authentication for user authentication.

Token Authentication is the process of generating a random string and sending it to the client (in the form of a cookie). It's intended to provide a simple mechanism to "reset" the authentication token (the secret) without needing to send the entire token to the client, allowing for a more secure reset process.

Session Authentication is a way to authenticate the client that is already connected to your system. Example: User clicks "Log In". Server generates a random string, sets a cookie, and sends it to the client. User logs in and saves the cookie. The cookie is sent to the server every time the client connects. If the cookie has not been set, the user is prompted for their credentials again.

If the user has already logged in before, then their credentials are saved on the server. The cookie is not sent to the server on subsequent login attempts.

Tokens are useful for keeping your session secure when you have a mobile application, because you can't send the entire cookie in a notification message.

What is token-based authentication?

Token-based authentication (TBA) is a form of authentication in which a user sends a token to the site that the user wishes to access, either directly to the site or through a proxy that redirects the user's request to the site. The following table describes some common features of this form of authentication: Authentication type. Features. What is involved in using this form of authentication? The client sends a request to the website that is being accessed. The server receives the request, checks the IP address of the requestor and the domain name on the HTTP request, and optionally compares this information against information stored on the server. If these checks pass, the server presents a form to the user. The form allows the user to enter a password. The server then either sends a session cookie back to the client or not. If the session cookie is sent, the user is logged in, and any subsequent requests from the client are routed to that session.

A common use for this form of authentication is a website that has a public area and an area for members only. When a member enters their credentials, they are forwarded to the "members-only" area. A session cookie is returned to the client that can then be used to send requests to the website, although only members have access to the "members-only" area.

How does token-based authentication compare with other authentication methods?
