Allthenticate is a passwordless authentication company that provides mobile-based identity and access management solutions for organizations. The company was founded based on academic research from institutions including CMU, UNC, MIT Lincoln Laboratory, and UCSB, with the goal of eliminating passwords and traditional authentication methods. The core product is a smartphone-based authentication platform that uses Bluetooth Low Energy (BLE) proximity detection, FIDO2 certification, and X.509 certificate-based cryptographic identity to authenticate users to computers, websites, servers, and physical access control systems (e.g., office doors). Users are authenticated automatically when their phone is detected nearby, and sessions are locked when they walk away — without requiring passwords, one-time codes, or push notification approvals. The platform supports integration with major identity providers (Microsoft Entra ID, Okta, Ping Identity) via SAML and OIDC for SSO, as well as SSH key management for developer workflows. It is compatible with Windows, macOS, Linux, iOS, and Android, and integrates with tools such as GitHub, GitLab, AWS, Azure, Google Cloud, Microsoft 365, and Google Workspace. Allthenticate uses a decentralized architecture designed to eliminate single points of failure, meaning credentials cannot be stolen even if servers are compromised. The company states it does not collect personally identifiable information and does not sell user data. The primary target market is small and medium-sized businesses, particularly tech companies, with pricing tiers ranging from a free personal plan to enterprise packages. A patented "Rescue Mission" feature allows users to recover access via trusted contacts without IT helpdesk involvement.
