  2. How the user name and password are sent to server when we user AD B2C authentication for our websites?
  3. How the passwords are stored on AD B2C?
  4. What are the security measure are taken from Microsoft to safe user's data in AD B2C? Do we have some certifications like ISO27001?

    Hi @Ankit Kumar , thanks for your question.

    1. Yes, by default all Azure resources are. In the event of a failure, your data will transferred to the closest region.
    2. If you're asking about authentication protocols, we use OpenID Connect and OAuth 2.0.
    3. We use password hash synchronization.
    4. We have an immense amount of compliance requirements, globally and regionally. ISO27001 is included in that. Here's a small blog post detailing how we keep your data safe.
    5. For SSO we can use the SAML protocol.

    Please let me know if you have any questions and I can help you further!
