SecSign ID by SecSign is a comprehensive two-factor authentication (2FA) solution designed to secure user logins for various systems, applications, and services. It utilizes advanced cryptography, including 2048-bit encryption and ECC keys, to protect user identities and data. SecSign ID supports multiple authentication methods, including mobile apps (iOS and Android), desktop applications (Windows, macOS, and Linux), hardware FIDO tokens, platform authenticators, smart cards, Time-based One-Time Passwords (TOTP), and email One-Time Passwords (OTP). The solution employs a challenge-response authentication mechanism with 2048-bit RSA key pairs, where the private key is securely stored on the user's device and never transmitted. SecSign ID can be deployed on-premise, in the cloud (such as AWS), or as a hybrid solution, offering flexibility for different organizational needs. It integrates with various systems including Atlassian products (Jira, Confluence, Crowd, Bitbucket, Bamboo), Active Directory, LDAP, OAuth2, OpenID Connect, and supports SAML for Single Sign-On (SSO) capabilities. The product is FIDO certified, enabling support for the FIDO2/WebAuthn standard for passwordless authentication.
