Relying only on passwords to protect sensitive information is dangerous. Ory's multi-factor authentication lets you guard access with passkeys, biometrics, and authenticator devices so a leaked password or lost laptop doesn't compromise your business.
Multi-factor authentication: the best defense against account takeovers
Multi-factor authentication stops 99.9% of attempted account takeovers in their tracks and keeps user data safe from malicious actors with the auth, audit, and recovery flows every security team needs.
Mitigate security risk
Over one billion passwords leak every year, and breaches are commonplace. Multi-factor authentication is the gold standard to protect your users and your company.
Passwordless MFA and second-factor methods
Choose from second-factor and passwordless methods: TOTP and authenticator apps, WebAuthn, FIDO2 security keys, passkeys, SMS one-time codes, and lookup secrets. Mix factors to fit each app's risk profile.
Adaptive enforcement
Choose where and when to enforce second-factor authentication based on threat modeling or user-account risk grading. Step up only when the risk warrants it.

The case for device binding: what it actually protects
Most authentication proves someone holds the right credential, not which device they're holding it on. Device binding (also called device authentication) closes that gap: a private key generated in a phone's secure hardware, attested by Apple or Google, and used for step-up approval or full passwordless login via PIN or biometrics.
