BankVault MasterKey

BankVault MasterKey is an invisible, passwordless multi-factor authentication (MFA) solution designed for SaaS platforms. It authenticates users without requiring passwords, software installation, or any user-side setup or configuration. Authentication is handled in a single step rather than the traditional two-step MFA process. The system operates using a decentralized web protocol that is FIDO2-compliant, and trust is enforced independently of the browser, device, or network — meaning authentication remains secure even when the end-user's device is compromised. Key characteristics of the approach: - Credentials are never entered, stored, or exposed in the browser, eliminating exposure to Man-in-the-Browser (MitB) attacks - No passwords means no credential interception, reuse, or account recovery burden - Users onboard instantly with no software to download or configure - The open-source API can be integrated using approximately 20 lines of code with no backend changes required - No-code plugins are available for leading SaaS marketplaces MasterKey is positioned as a complement to existing SSO and IAM solutions rather than a replacement. It does not rely on OAuth or social media authentication, one-time passcodes (OTPs), or password managers. The product targets the problem of registration and login abandonment in SaaS platforms, which industry data attributes to friction in the authentication process. By removing that friction, the vendor claims improvements in customer acquisition and engagement metrics.
