External ID passkey guidance drops custom URL prerequisite and links deletion samples

The week’s two External ID updates focused on passkey documentation: setup guidance removed the custom URL domain prerequisite, while app-sample listings added links for listing, registering, and deleting passkeys and removed a prior warning.

For Entra administrators

Administrators reviewing passkey setup should no longer treat a configured custom URL domain as a documented prerequisite. Teams using the JavaScript, React, or single-page application samples should note that the former test-tenant-only warning is no longer displayed; the supplied guidance states that no action is required.

This period briefing was generated by AI from the tracked Microsoft Learn and Message Center changes.
