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 ...
Tells the browser to refresh the page or redirect to a different URL, after a given number of seconds (0 meaning immediately); or when a new resource has been created [clarification needed]. Header introduced by Netscape in 1995 and became a de facto standard supported by most web browsers. Eventually standardized in the HTML Living Standard in ...
Acts as an authentication provider to other modules, like mod_auth_basic, mod_auth_digest, and mod_auth_form, by checking passwords that contain a variable portion based on the HOTP/OATH one-time password algorithm defined in RFC 4226. [18] mod_authn_socache: Versions 2.3 and newer: Included by Default: Apache Software Foundation: Apache ...
The response must include a WWW-Authenticate header field containing a challenge applicable to the requested resource. See Basic access authentication and Digest access authentication. 401 semantically means "unauthenticated", the user does not have valid authentication credentials for the target resource. 402 Payment Required Reserved for ...

Web Authentication (WebAuthn) is a web standard published by the World Wide Web Consortium (W3C). [1] [2] [3] WebAuthn is a core component of the FIDO2 Project under the guidance of the FIDO Alliance. [4] The goal of the project is to standardize an interface for authenticating users to web-based applications and services using public-key ...
Header Identifies which algorithm is used to generate the signature. In the below example, HS256 indicates that this token is signed using HMAC-SHA256. Typical cryptographic algorithms used are HMAC with SHA-256 (HS256) and RSA signature with SHA-256 (RS256). JWA (JSON Web Algorithms) RFC 7518 introduces many more for both authentication and ...
