How does token based authentication work?
Token based authentication works by ensuring that each request to a server is accompanied by a signed token which the server verifies for authenticity and only then responds to the request.
Is OAuth token based authentication?
OAuth doesn’t share password data but instead uses authorization tokens to prove an identity between consumers and service providers. OAuth is an authentication protocol that allows you to approve one application interacting with another on your behalf without giving away your password.
How does a token-based authentication system work?
Once authenticated, the client receives from the authentication server a signed and often encrypted authentication token that it then appends to every request sent to applications that it wants to interact with. The app verifies the integrity of the authentication token and parses its contents.
How are tokens used in single page applications?
Token-based authentication systems are growing in popularity, especially for Single Page Applications (SPAs). When a user authenticates using their username and password, they’re issued a token, containing an authentication ticket that can be used for authentication and authorization.
What does it mean when a server issues a token?
With token authentication, a secondary service verifies a server request. When verification is complete, the server issues a token and responds to the request. The user may still have one password to remember, but the token offers another form of access that’s much harder to steal or overcome.
How is malicious JavaScript used to read authentication tokens?
Malicious JavaScript (JS) that reads authentication tokens is injected by an attacker to a trusted site. It is then served by the site to its users, and executed by their browsers where it reads authentication tokens from the user’s machine and sends them to the attacker.
