Microsoft Entra: Self-service password reset CAPTCHA protection updated

Microsoft Entra is replacing the legacy CAPTCHA in self-service password reset with backend throttling and behavior-based detection to enhance security and user experience. The update, requiring no configuration, will roll out worldwide from late July to mid-August 2026, with no impact on users or admins.

[What and Why]

We are updating bot protection in Microsoft Entra self-service password reset (SSPR) by replacing the legacy CAPTCHA with modern backend throttling and behavior-based abuse detection. This change improves security, accessibility, and reliability by reducing friction for users while strengthening protection against automated attacks and account enumeration. No configuration changes are required. This change is fully managed by Microsoft.

[Rollout Schedule]

General Availability (Worldwide): Rollout will begin in late July 2026 and is expected to complete by mid-August 2026.
