Passkey authentication is a form of Strong Customer Authentication (SCA) that saves a passkey on the cardholder's device. The first time the cardholder authenticates a card transaction by completing an SCA challenge, they register their biometrics or a PIN code as a passkey. For all subsequent transactions on the same device, they authenticate using the registered biometrics or PIN instead of completing a new SCA challenge. ## Requirements | Requirement | Description | | -------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | **Integration type** | [Adyen Issuing](https://docs.adyen.com/issuing) | | **Limitations** | * Passkey authentication is not supported for card transactions that are enrolled in 3d secure using [Out-of-band authentication](https://docs.adyen.com/issuing/3d-secure/oob-auth-sdk). * Passkey authentication is only supported for native password managers. Native password managers are built-in credential management systems developed directly by the operating system (OS) or hardware manufacturer. Third-party password managers are not supported. * You can register a maximum of five passkeys to a single card. To register more than five passkeys, reach out to our [Support Team](https://ca-test.adyen.com/ca/ca/contactUs/support.shtml?form=other). | | **Setup steps** | Before you begin, you must enroll the cardholder's cards in 3d secure using [One-time password authentication](https://docs.adyen.com/issuing/3d-secure/password-otp). | ## Register a passkey The cardholder can register their passkey the first time they make an online payment, and get redirected to a 3D Secure authentication page. If no passkey is registered, the cardholder continues to use the [one-time password authentication method](https://docs.adyen.com/issuing/3d-secure/password-otp) for all transactions. To register a passkey, the cardholder must: 1. Complete the SCA challenge successfully, using the [one-time password authentication method](https://docs.adyen.com/issuing/3d-secure/password-otp).

When prompted to register a passkey, select **Create passkey**. You can register a maximum of five passkeys to a single card. To register more than five passkeys, reach out to our [Support Team](https://ca-test.adyen.com/ca/ca/contactUs/support.shtml?form=other).

Set up their passkey with their preferred authentication method: * If their device supports biometrics, they can register their biometrics. * If their device does not support biometrics, they must set up a PIN code.

Authenticate using the biometrics or PIN code they just registered.\ [![Authenticate with biometrics or pin code](/images/6/8/a/6/f/68a6fbbb396817f96b658c41edae17003a38c2bd-authenticate-with-biometrics-or-pin.png)](https://docs.adyen.com/user/pages/docs/07.issuing/22.3d-secure/03.passkeys/authenticate-with-biometrics-or-pin.png) 5. If successful, the cardholder receives a confirmation that the passkey was created successfully. Select **Continue**. [![Passkey created](/images/1/4/6/6/2/14662ce6e83b9012315fdfa37f82c176581e6f89-passkey-created.png)](https://docs.adyen.com/user/pages/docs/07.issuing/22.3d-secure/03.passkeys/passkey-created.png) The passkey is saved to the cardholder's password manager. For all future transactions on the same device, the cardholder can authenticate using the biometrics or PIN they registered. ## Authenticate using a passkey After a cardholder has registered a passkey, they can use it to authenticate all subsequent transactions on the same device. To do this, they must do the following: 1. When prompted to authenticate their transaction, select **Authenticate with Passkey**.\ [![Choose authentication method](/images/e/0/4/e/2/e04e243a4a731659ee0c9a92f76ad9e79f1d9d33-choose-auth-method.png)](https://docs.adyen.com/user/pages/docs/07.issuing/22.3d-secure/03.passkeys/choose-auth-method.png) 2. Provide their registered biometrics or PIN code.\ [![Authenticate with biometrics or pin code](/images/6/8/a/6/f/68a6fbbb396817f96b658c41edae17003a38c2bd-authenticate-with-biometrics-or-pin.png)](https://docs.adyen.com/user/pages/docs/07.issuing/22.3d-secure/03.passkeys/authenticate-with-biometrics-or-pin.png) 3. If the authentication is successful, select **Continue**. This completes the SCA challenge and the payment becomes ready for authorization. [![Authentication complete](/images/b/3/e/9/6/b3e9696ed4d3f3ee027bdf270b173baa6aea32ad-authentication-complete.png) ](https://docs.adyen.com/user/pages/docs/07.issuing/22.3d-secure/03.passkeys/authentication-complete.png). If the authentication fails, the cardholder can either retry the authentication, or authenticate using the [one-time password authentication method](https://docs.adyen.com/issuing/3d-secure/password-otp). ## Delete a passkey You may want to delete a passkey if: * The device where the passkey is registered is lost, stolen, or no longer in use. * You want to register a new passkey but have already reached the maximum of five passkeys for a single card. * You no longer want to use passkey authentication on a specific device. To delete a passkey, reach out to our [Support Team](https://ca-test.adyen.com/ca/ca/contactUs/support.shtml?form=other). After a passkey is deleted, the cardholder can no longer use it to authenticate transactions. For future transactions on that device, the cardholder will need to authenticate using the one-time password authentication method.
