Open Source Authentication for a Secure World.
CryptoGate is an open-source authentication platform designed to deliver next-generation security for applications and organizations that prioritize privacy and strong protection against account takeovers. Unlike traditional login systems that rely on passwords stored on servers, CryptoGate uses modern cryptography to create a zero-knowledge authentication system. This means passwords and private keys never leave the user’s device, and the server only verifies cryptographic proofs rather than storing sensitive secrets.
At its core, CryptoGate replaces vulnerable password-based authentication with device-bound cryptographic identities. Each user device holds its own secure keypair, allowing seamless yet highly secure logins across phones, laptops, and hardware security keys. The platform supports industry-standard passkeys (WebAuthn) and FIDO2 hardware keys, making phishing-resistant authentication accessible by default.
One of CryptoGate’s most powerful features is its optional distributed multi-factor authentication. Instead of depending on a single second factor, users can require approval from multiple trusted devices (for example, a 2-of-3 setup involving a phone, laptop, and hardware token). This approach significantly raises the bar for attackers while remaining user-friendly. Additional capabilities include end-to-end encryption of identity credentials, offline recovery using secure key shards, and the ability to add, revoke, or limit individual devices without forcing a full account reset.
CryptoGate is built with transparency and auditability in mind. The entire system is self-hostable, released under the AGPL-3.0 license, and designed for integration with modern standards such as OAuth2, OpenID Connect, and SAML. Developers and organizations can deploy it on their own infrastructure, ensuring full control over authentication data and compliance requirements.
By combining zero-trust principles, strong cryptography, and flexible multi-device security, CryptoGate offers a robust, privacy-first alternative to conventional authentication solutions — empowering users and developers to protect digital identities in an increasingly hostile online environment.
