During FIDO2 security key registration, Microsoft Entra ID users may see an operating system or browser-generated prompt for creating a passkey on another device, such as a phone or tablet. In some cases, a QR code is shown to facilitate this option.
Entra ID FIDO2 registration may now offer cross-device passkey creation
December’s substantive Entra change was a Microsoft 365 Message Center notice about the FIDO2 security key registration experience. During registration, users may see an operating system- or browser-generated prompt to create a passkey on another device, such as a phone or tablet; some users may instead see a QR code. The supplied evidence does not identify a preview or general-availability milestone, policy change, retirement, or required administrator action.
- FIDO2 registration can present a cross-device passkey flowEntra ID
The registration experience may invoke a prompt generated by the operating system or browser to create a passkey on another device, including a phone or tablet. In some cases, a QR code facilitates that flow. This is a behavior change in registration—not evidence of a new policy, rollout milestone, or administrative requirement.
The impact is primarily to the user and support experience. Administrators and support teams should recognize the cross-device passkey prompt or QR code as an expected possibility during FIDO2 registration. No configuration change, migration, or mandatory action is identified in the supplied evidence.
