Authen2cate vs Rublon Multi-Factor Authentication: Side-by-Side Comparison (2026)

Authen2cate

Startups and early-stage SMBs needing to lock down employee access without overcomplicating identity infrastructure should evaluate Authen2cate, particularly if they're already running Active Directory on premises. The platform delivers SSO and MFA in one product, which eliminates the tax of bolting separate tools together, and its hybrid deployment model means you don't have to rip out existing directory infrastructure. Skip this if you need SCIM provisioning, fine-grained access policies, or plans to scale past a few dozen users; the pricing and feature set clearly target the sub-100-person window.

Rublon Multi-Factor Authentication

Startups and mid-market companies needing MFA without the sprawl of enterprise IAM platforms should move fast on Rublon Multi-Factor Authentication; its push notification and passkey support eliminate the friction that kills adoption, and automatic enrollment on first login means you're not managing onboarding manually. FIDO2 and RADIUS integration for VPN access cover the two deployment scenarios that actually matter for teams splitting time between office and remote. Steer clear if your org has already standardized on Okta or Azure AD for SSO; Rublon's strength is MFA acceleration, not replacing your identity platform.
