| November 5,2025.    | [Mastercard Payment Passkey Enrollment](https://developer.mastercard.com/issuer-enrollment/documentation/use-cases/passkeys/index.md) enables issuers to let cardholders authenticate online transactions using biometrics such as fingerprint or face recognition---offering a faster, password-free, and phishing-resistant experience. Built on **Mastercard's Token Authentication Service (TAS)**, it enhances transaction security, approval rates, and user convenience. Issuers can integrate via simple API calls to enroll, bind, and manage passkeys through their own channels or during checkout.                                                                                                                                                                                                      |
| August 28, 2025.    | To support annual public key rotation and eliminate issues related to Key ID (KID) mapping, Mastercard has introduced [separate URLs](https://developer.mastercard.com/issuer-enrollment/tutorial/key-management-click2pay/index.md#public-keys-mastercard-provides) for each key type in Sandbox and Production environments.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      |
| June 6, 2025.       | We have ready-to-use json packages for all the [Issuer-Enrollment APIs](https://developer.mastercard.com/issuer-enrollment/documentation/api-reference/apis/index.md) available on the [Insomnia collection](https://developer.mastercard.com/issuer-enrollment/documentation/insomnia-collection/index.md) page.
