Session ID. In computer science, a session identifier, session ID or session token is a piece of data that is used in network communications (often over HTTPS) to identify a session, a series of related message exchanges. Session identifiers become necessary in cases where the communications infrastructure uses a stateless protocol such as HTTP.
In computer science and networking in particular, a session is a time-delimited two-way link, a practical (relatively high) layer in the TCP/IP protocol enabling interactive expression and information exchange between two or more communication devices or ends – be they computers, automated systems, or live active users (see login session ).
Access token. In computer systems, an access token contains the security credentials for a login session and identifies the user, the user's groups, the user's privileges, and, in some cases, a particular application. [1] In some instances, one may be asked to enter an access token (e.g. 40 random characters) rather than the usual password (it ...
A login page may have a return URL parameter, which specifies where to redirect back after logging in or out. For example, it is returnto= on this site. In the case of websites that use cookies to track sessions, when the user logs out, session-only cookies from that site will usually be deleted from the user's computer. In addition, the server ...
JSON Web Token ( JWT, suggested pronunciation / dʒɒt /, same as the word "jot" [1]) is a proposed Internet standard for creating data with optional signature and/or optional encryption whose payload holds JSON that asserts some number of claims. The tokens are signed either using a private secret or a public/private key .
In the context of an HTTP transaction, basic access authentication is a method for an HTTP user agent (e.g. a web browser) to provide a user name and password when making a request. In basic HTTP authentication, a request contains a header field in the form of Authorization: Basic <credentials>, where <credentials> is the Base64 encoding of ID ...
The Central Authentication Service ( CAS) is a single sign-on protocol for the web. [1] Its purpose is to permit a user to access multiple applications while providing their credentials (such as user ID and password) only once. It also allows web applications to authenticate users without gaining access to a user's security credentials, such as ...
Due to how single sign-on works, by sending a request to the logged-in website to get a SSO token and sending a request with the token to the logged-out website, the token cannot be protected with the HttpOnly cookie flag and thus can be stolen by an attacker if there is an XSS vulnerability on the logged-out website, in order to do session ...
