azure-ad-b2c - Azure AD B2C 用户迁移成本

Question

如果B2C对用户迁移收费，我似乎找不到书面答案？有没有人有这个问题的引用？假设我有 100 万用户想要迁移到 B2C。免费用户达到 5 万后，我会为每个用户收费吗？
通过查看有关刷新 token 和其他操作的其他问题，并询问它似乎仅在颁发 ID 或访问 token 时才计入配额。有没有人在实践中做过这种大规模的用户迁移并且没有被收费？很大一部分用户处于非事件状态，我不想因迁移他们而产生费用。

Answer 1

遗憾的是，我没有经历过如此大规模的迁移，只有几万用户。
但根据文档，每月活跃用户 (MAU) 定价模型仅对在给定月份内进行身份验证的用户收费(50 000 MAU 是免费的)。
从定价页面引用( https://azure.microsoft.com/en-us/pricing/details/active-directory/external-identities/ ):

Who is considered a "monthly active user"?

A monthly active user (MAU) is a unique user that performs an authentication within a given month. For example, a user that authenticates multiple times within a given month is counted as one MAU. Customers are not charged for a MAU’s subsequent authentications during the month, nor for inactive users.

此外:

What is considered an authentication?

Authentications may include:

• Active, interactive login by the user;
• Passive, non-interactive login (such as single sign-on, sign-up, sign-in, token refresh, and password change)

Additional operations that are counted as an authentication include: login to a portal; redeeming an invitation; authenticating to perform an admin action; and when an application exchanges a refresh token for a new identity token or access token for that user.

因此，通过 Microsoft Graph API 添加用户不会算作“事件用户”或“身份验证”。
让他们登录以重置密码作为迁移的一部分很重要。
因此，如果您的迁移仅涉及通过 Graph API 创建用户而不是让用户登录/重置他们的密码，那么他们应该不会对您产生任何费用。
