Does Okta Identity Engine maintain screen reader focus during MFA transitions in SSPR?

When implementing the Self-Service Password Reset (SSPR) workflow in Okta Identity Engine (OIE), the user experience often involves a transition from the initial identity verification page to a Multi-Factor Authentication (MFA) challenge.

For users relying on assistive technologies, consistent focus management is critical to ensure that the screen reader immediately identifies the new MFA prompt without requiring the user to manually navigate through the entire DOM again.

There is uncertainty regarding whether the hosted Okta sign-in page automatically shifts focus to the MFA challenge container or if the focus remains on the previous submission trigger, potentially creating a navigation gap for WCAG compliance.

• Does the OIE SSPR flow programmatically move focus to the MFA challenge upon page update?
• Which specific ARIA attributes are utilized to notify screen readers of the dynamic content change during the reset process?
