Hi Andrew Barber,
Thank you for posting in the Q&A Forums.
Why do I need to migrate?
Better Security: b2clogin.com provides a more direct path to authentication, reducing potential security risks.
Better performance and reliability: The new endpoint is designed to better handle authentication traffic, improving performance and reliability.
Functionality improvements: Some future functionality updates may only be available to tenants using b2clogin.com.
How do I handle this warning?
Ensure all custom domains and policies are updated: Review all of your user flows (also known as policies) and custom domain settings to ensure they are updated to use b2clogin.com. This includes updating the redirect URIs and authorization/token endpoints in your application configuration.
TEST: Thoroughly test all of your authentication processes to ensure they are working properly on the new endpoints before fully migrating. This includes registration, login, password reset and any multi-factor authentication processes.
Update documentation and communications: If your application or service relies on external users or partners, make sure they are also aware of the change and are ready to update accordingly.
Progressive Migration: If possible, consider migrating users to a new endpoint gradually to monitor and resolve any potential issues.
Monitoring and feedback: Continuously monitor your authentication process after migration and provide Microsoft with any feedback or issues encountered.
Post-migration benefits
Enhanced security: Protect your users and data by reducing the potential attack surface.
Better user experience: Reduce authentication delays and improve the overall user experience.
Long-term compatibility: Ensures that your services will be able to take advantage of future features and improvements in Azure AD B2C.
Best regards
