Release Notes - FIDO Connector

The following lists public releases of new features, resolved issues, and known limitations for new versions of the Yubico FIDO Connector App.

Release 1.1.4 (22 August 2025)

New Features & Enhancements

  • Get user using UPN (User Principal Name): Previously, in the JSON request the user_id was provided as Object ID. To enhance the user experience, the input now allows user_id to be provided either as Object ID, for example "user_id": "123456-abc-123456-xyz", or as UPN, for example "user_id": "username@yubico123.sample.com".
  • Connector container app version: Functionality has been updated to show the application version. /v1/status now returns the "FIDO_CONNECTOR_VERSION": "string" field displaying the version of the FIDO Connector application software.

Resolved Issues

  • Connector API response: Previously the API was returning a “500 Internal Server Error” message, for example when an invalid YubiEnterprise API token was used. To provide more guidance to the user, the error message has been changed to show a “401 Unauthorized” error message instead.

Release 1.1.1 (25 June 2025)

New Features & Enhancements

  • PIN length changed to 4-63. The validation in the API accepts a PIN length value between 4 to 63, inclusive. This means you can enter any number from 4 up to 63 (including either 4 or 63) as PIN length. See API Reference.
  • Support for address validation override. An address_validation_bypass flag (true/false) has been added to the API. If set to “true”, the API will accept the provided address without further validation. See Address Validation.

Release 1.0.0 (3 April 2025)

First release of the Yubico FIDO Connector App. The application is deployed to a Microsoft Azure subscription and handles most of the Customer Orchestration complexities. For more information about included features, see Yubico FIDO Connector App.
