Opportunities**
Improved User Experience for Guest Access
The new guest authentication experience allows users to authenticate through their home organization's sign-in page, which enhances usability and reduces confusion. This change can lead to higher satisfaction and engagement from guest users, making collaboration smoother and more efficient.
- next-steps: Communicate the upcoming changes to all stakeholders and guest users. Update internal documentation to reflect the new authentication process and provide training sessions to familiarize users with the new experience.

Streamlined B2B Collaboration Management
With the new authentication experience, organizations can streamline the management of guest accounts by reducing the number of authentication-related issues. This can lead to decreased support requests and administrative overhead, allowing IT teams to focus on other critical tasks.
- next-steps: Assess current B2B collaboration configurations and identify areas for improvement. Implement monitoring tools to track guest user experiences and gather feedback for continuous improvement.

Enhanced Security Posture
By redirecting guest users to their home organization's sign-in page, the new authentication method adds an extra layer of security, as users are more likely to recognize and trust their own organization's sign-in process. This can reduce the risk of phishing attacks and unauthorized access.
- next-steps: Review and update security policies to align with the new authentication process. Conduct training sessions for IT staff on potential security implications and best practices for managing guest access.
