Azure AD B2C billing - What is a Montly Active User?

Question

If I set the users token to last for say 1 year, will that reduce my costs? or the simple fact of checking for the validity of that token will (with a call to my custom api for example) will constitute as a MAU?

@Leonardo Ferreira

An 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.

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.
