Hello @Shilpa Prajapati
Thank you for reaching out to the Microsoft Q&A platform.
Azure AD B2C supports a sandbox mode that allows you to test and experiment with your policies and user flows without affecting your production environment.
Note that azure Sandbox isn't intended for production use. The deployment uses some best practices, but others intentionally aren't used in favor of simplicity and cost. A sandbox is ideal for accelerating Azure projects. You can use the sandbox for activities like:
- Self-learning
- Hackathons
- Testing
- Development
