WebAuthn. 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 ...
Google Authenticator is a software-based authenticator by Google. It implements multi-factor authentication services using the time-based one-time password (TOTP; specified in RFC 6238) and HMAC-based one-time password (HOTP; specified in RFC 4226), for authenticating users of software applications.
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 ...

Description. [edit] The ChaCha20-Poly1305 algorithm takes as input a 256-bit key and a 96-bit nonceto encrypt a plaintext,[1]with a ciphertext expansion of 128-bit (the tag size). In the ChaCha20-Poly1305 construction, ChaCha20 is used in counter mode to derive a key stream that is XORedwith the plaintext.

HMAC-based one-time password ( HOTP) is a one-time password (OTP) algorithm based on HMAC. It is a cornerstone of the Initiative for Open Authentication (OATH). HOTP was published as an informational IETF RFC 4226 in December 2005, documenting the algorithm along with a Java implementation. Since then, the algorithm has been adopted by many ...
