I recently started studying ADB2C. Therefore, I would like to know the maximum number of users I can register with ADB2C.

Microsoft will happily bill you for as many users as you want past the 50,000 free threshold. https://azure.microsoft.com/en-us/pricing/details/active-directory/external-identities/

CodePudding user response：

You can create 50M users. You do not need to contact Microsoft. AAD B2C tenants auto scale for number of objects. You are not charged for users. You are charged for unique authentications per month.
