BankVault MasterKey vs Duo Single Sign-On (SSO): Side-by-Side Comparison (2026)

BankVault MasterKey

Startups and SMBs tired of password reset tickets and phishing-resistant auth that requires hardware keys should run a pilot of BankVault MasterKey; it kills both problems with zero user friction or infrastructure work. The FIDO2-compliant decentralized protocol runs entirely in the browser without installing software or changing your backend, and onboarding takes minutes instead of weeks. Skip this if your org needs deep IAM governance or identity analytics; MasterKey bolts onto existing SSO systems rather than replacing them, so it's an auth layer, not a complete identity platform.

Duo Single Sign-On (SSO)

Mid-market and enterprise teams tired of password resets and MFA friction will find Duo SSO's passwordless authentication and adaptive access policies actually reduce help desk tickets without sacrificing security. The platform's support for both cloud and on-premises applications through SAML 2.0 and OIDC, plus pre-built integrations for hundreds of apps, means you're not building custom connectors for six months. Skip this if your organization needs deep identity governance, entitlement management, or advanced threat detection; Duo SSO prioritizes frictionless authentication over the broader identity lifecycle controls that larger enterprises typically demand from their IAM platform.
