FIDO2 and WebAuthn · Passwordless Authentication · Evidence & Implementation Kit
Deploy phishing-resistant passwordless authentication with FIDO2, without designing the relying-party controls yourself.
Every FIDO2 and WebAuthn deployment concern handed to you as an adopt-ready control, from origin binding and attestation through passkeys, account recovery and enterprise policy, with the evidence a security reviewer examines.
Passwordless-ready in a weekend, not a quarter.
Here is the honest situation. Passwordless authentication with FIDO2 and WebAuthn kills phishing, because credentials are bound to your origin and there is no shared secret to steal. But a real deployment is more than turning it on: origin and challenge validation, attestation and the metadata service, user verification, the passkey sync versus hardware-bound tradeoff, and account recovery that does not reintroduce a phishable factor. Getting those relying-party controls right, and evidencing them, is real work, and a recovery flow that falls back to a one-time code is exactly where a passwordless rollout quietly reintroduces the risk it was meant to remove.
This Kit removes that design. It is every FIDO2 and WebAuthn control written as an adopt-ready control you personalize in a weekend, with the evidence a security reviewer examines.
What you get, the moment you buy
32
Deployment concerns as adopt-ready controls. Every FIDO2 and WebAuthn control, from origin binding and attestation through passkeys, credential lifecycle, recovery and enterprise policy, written so you personalize and apply it as a relying party.
32
Evidence-they-examine checklists. For each control, exactly what a security reviewer examines, plus where passwordless rollouts go wrong, so you close the gap first.
1
Passwordless Control Matrix, pre-built. Every control in a working spreadsheet, ready to record status and evidence location across the deployment.
1
Gap & Readiness Assessment. Score each control and the workbook returns your readiness as a single percentage, and exactly what to fix next.
Grounded in the FIDO2 and WebAuthn specifications, with origin binding for phishing resistance, attestation and the metadata service, user verification, and account recovery called out, mapped to NIST 800-63B AAL2 and AAL3. Editable Word and Excel files.
Recovery is where passwordless quietly fails
A passwordless deployment is only as phishing-resistant as its weakest recovery path. If account recovery falls back to a one-time code or a security question, the phishing resistance is gone. This Kit makes recovery a first-class control, so the flow that undoes most rollouts is designed to stay phishing-resistant.
What one control looks like
This is origin binding for phishing resistance, the property that makes FIDO2 unphishable. All 32 are built to this depth.
FIDO-12 Origin binding enforcement PHISHING RESISTANCE
Implement this control
During the authentication ceremony the [Relying Party] shall verify that the origin in the client data is an exact expected origin and that the relying-party identifier hash in the authenticator data matches the configured relying-party identifier, rejecting any assertion whose origin or identifier does not match so that credentials presented to a look-alike phishing site are never accepted.
Engineering note.
The browser refuses to release a credential to the wrong origin; the server must still refuse assertions carrying an unexpected origin.
Evidence a security reviewer examines
- Server verification code enforcing origin and RP ID hash checks
- Configured list of valid origins and the relying-party identifier
- Negative tests confirming mismatched origins are rejected
- Log entries showing rejected assertions from unexpected origins
Common finding they raise: Wildcarding origins, accepting any subdomain, or disabling the RP ID check to fix a login bug reintroduces phishing exposure that the standard exists to prevent.
Why this is not another template pack
- The evidence is the point. A control you cannot evidence is a claim. This tells you exactly what a security reviewer examines and where passwordless rollouts go wrong, for every control.
- Phishing resistance, done right. Origin binding, challenge freshness, signature counters and user verification are built as controls, the mechanisms that make FIDO2 phishing-resistant rather than just passwordless.
- Built on a mapped compliance corpus, not one person's opinion, from a graph of thousands of controls across standards.
- It compounds. FIDO2 maps onto NIST 800-63B AAL2 and AAL3 phishing-resistant authentication, so this work supports your identity assurance program.
Who buys this
Security and identity teams deploying passwordless authentication, the relying-party engineers who own it, and consultants standing up FIDO2. Whether it is a first rollout or an enterprise policy, you save weeks and walk in with the controls and evidence ready.
By the end of the weekend you will have
✓ An adopt-ready control for all 32 items
✓ A completed passwordless control matrix
✓ The evidence a security reviewer examines
✓ Your origin binding and recovery flows defined
✓ A readiness percentage and a fix list
✓ The common rollout failures designed out
Common questions
Is it really editable? Yes. Word and Excel files you own and adapt. No portal, no subscription.
Does it cover passkeys? Yes. Synced passkeys versus hardware-bound authenticators, and the assurance tradeoff, are built as controls.
Does it cover account recovery? Yes. Phishing-resistant recovery and multi-authenticator enrollment against lockout are their own controls, because recovery is where rollouts go wrong.
Does it map to NIST 800-63B? Yes. The controls map to AAL2 and AAL3 phishing-resistant authentication, with the hardware-binding note for AAL3.

Do not design relying-party controls from scratch.
Every FIDO2 control is fast to adopt with the Kit. It is instant, and it is guaranteed.
