Azure AD B2C - Email verification/approval after sign-up

Question

Would like users to sign-up without email verification(There is an option to disable this in B2C GUI) and an email should be sent with a link that users can click to activate the account. Doesn't look to be possible out of the box. Is there a way to accomplish this while also making sure that the email activation is secure and not prone to brute force attack?

Answer 1

These some example code here.

The repository also contains a good write-up "Implementing an invitation flow" which will help.

The security requirement is achieved by using a signed JWT to transfer the claims.
