Solution

Passwordless & MFA — without the OTP fatigue.

Replace shared-secret passwords with hardware-bound FIDO2 credentials. Phishing-resistant by construction. Cards, USB keys, and biometric tokens — enterprise-deployable, audit-friendly, no battery to die in someone’s drawer.

What this actually solves

  • Credential stuffing. The attacker has 12+ billion leaked passwords. With FIDO2 there is no password to steal — the per-origin keypair is generated and stored in the authenticator and never leaves it.
  • Phishing. A FIDO2 credential is bound to the relying-party origin in the browser. A look-alike phishing site cannot harvest a usable credential because the browser will not authorise the wrong origin.
  • OTP interception / SIM swap. SMS and TOTP both have a real-time-interception window. Hardware-bound MFA does not.
  • UX fatigue. Tap a card, touch a key. No 30-second OTP entry. Resident credentials drop the username field too.

Migration path from password+OTP

01

Pilot 100

Issue a pilot batch to one team. Validate IdP integration and user UX.

02

Allow alongside

FIDO2 added as a permitted MFA method alongside existing OTP / push.

03

Require for privileged

Privileged accounts require FIDO2. OTP retained as fallback only.

04

Workforce-wide

FIDO2 the default; password retained only as a fallback during enrollment.

05

Passwordless

Resident credentials — users don’t even type their username.

Pilot a passwordless rollout.

Tell us your IdP (Okta, Azure AD, Ping, ForgeRock, custom), target user count, and certification target. Pilot batches in 6–8 weeks.
