1Password Passkeys vs My1Login Single Sign-On (SSO): Side-by-Side Comparison (2026)

Security teams at startups and SMBs ready to ditch passwords will find 1Password Passkeys the fastest path to phishing-resistant authentication without rebuilding identity infrastructure. Passkey synchronization across Mac, iOS, Windows, and Android means users stay productive while biometric unlock eliminates the friction that kills adoption. Skip this if your organization needs deep integration with existing directory services or passwordless MFA for legacy apps; 1Password Passkeys works best for greenfield deployments and teams comfortable standardizing on new authentication workflows. Mid-market and enterprise teams managing hybrid Windows and web environments will get the most from My1Login Single Sign-On because it's one of the few IDaaS platforms that actually handles legacy desktop apps like Citrix and Remote Desktop alongside modern SAML applications without separate tooling. The platform's credential-based SSO for password-protected legacy systems means you're not forklift-replacing infrastructure to standardize on modern protocols. Skip this if your organization runs exclusively cloud-native SaaS; the Windows desktop strength is wasted overhead, and you'll find better value in vendors optimized for pure web application portfolios.
