How Auth0 Calculates Monthly Active Users (MAU)

Monthly Active Users (MAU) are part of the user quota for each Auth0 plan. The MAU count represents the number of unique user IDs that issue tokens within a given month. Auth0 considers a user active if they generate specific log events, and Auth0 still counts deleted users toward the quota if they were active during that month.

How does Auth0 calculate the Monthly Active Users count?

The Monthly Active Users (MAU) count represents the number of unique user IDs that issue tokens within a given month. If the same user ID issues 100 tokens, Auth0 counts it as one MAU within the month timeframe, regardless of how many applications a tenant issues tokens for.

Auth0 considers a user active in a given month if they generate a log of user activity with their user ID under one of the following events.

• s: Successful login.
• sepft: Successful exchange of password for token.
• ssa: Successful silent authentication.
• seoobft: Successful exchange of Password and OOB Challenge for Access Token.
• seotpft: Successful exchange of Password and OTP Challenge for Access Token.
• sercft: Successful exchange of Password and MFA Recovery code for Access Token.
• sertft: Successful exchange of Refresh Token for Access Token.
• seacft: Successful exchange of authorization code for Access Token.
• scoa: Success cross-origin authentication.
• sebns: Successful native social exchange.
• secte: Successful token exchange.

Refresh tokens do not affect the MAU count. Once Auth0 issues an access token to a user within the month, the user can receive unlimited access tokens while only generating one MAU count. Additionally, if an administrator deletes users after they become active, Auth0 still counts those users in the MAU for the month they were active.
