Read the illustrated customer guide

Try the customer sign-in example

PasswordFree · BigCommerce LoginFree · interactive example

Try the highlighted button or use the controls below.

Start at the store. An enrolled customer chooses PasswordFree to return to their account. Try the sign-in button in the store.

The same picture. The same number. Compare the black picture and code on the two screens. If they match, select Accept in the store. If anything looks wrong, select Decline.

Enrolled deviceReady when you are.

Try the highlighted button or use the controls below.

A sensitive operation is ready. The application sends a NoPass approval request to the person responsible. Start the request in the application.

The request reaches your phone. Open the push notification on the enrolled phone. The application waits while you check the request.

Check both screens. Then decide. Compare the black picture and number. If this is the request you intended, select Confirm on the phone, using the local confirmation configured for your device, such as fingerprint or Face ID.

Approved — back to application policy. Approval received. The application still applies its own permissions and execution policy before carrying out the operation.

Discuss one workflow

Prepare an evaluation without a sales gate.

Choose one interaction. These questions help you prepare an evaluation; they do not produce a security score.

Where does the interaction happen? Customer account Work application Sensitive operation AI-agent action Not sure yet

How does the person recognize the requesting service? An enrolled app verifies the authentication service Appearance or a familiar message I want to examine this

What already handles access? Existing MFA or passkeys An identity provider and application policies We need to map the current setup

Who starts the request? The person starts it A service or AI agent starts it We need to define when the request is expected

Who owns device changes and recovery? Our identity and support team Our service provider We need to define this

Your answers stay in this tab. Nothing is sent. Switching languages uses a temporary copy to restore your answers once. You choose whether to add the brief to a request.

A short workflow self-review
Start here	Questions to examine
Explore customer-account access.	Which customer-account integration fits the store or application? How does the person recognize the service on the returning visit? Who supports first enrollment and a changed device?
Explore workforce access.	Which application or workstation is the first access point? How will the configured integration use your existing identity setup? Who owns employee enrollment, device changes and offboarding?
Explore operation approval.	Which operation waits for the decision? How will the application correlate and handle the result? What happens after decline, expiry or a changed operation?
Explore a human-approval checkpoint.	Which agent action needs a person’s decision? How will the person know the action is expected? Who owns the application’s authorization and execution policy?
Start with the trust architecture.	Who are the people and services involved? How do both sides establish the enrolled relationship? Which decision should remain with the person?
