#Monthly active users
A user is active in a month when they sign in at least once that month (with any method), in a production tenant. Refreshing tokens doesn't count as a new sign-in. Sandbox users never count. Users are counted across all of an account's production tenants.
Above the included users, paid plans keep working and bill the extra users. The Free plan pauses new sign-ups at 110% of its limit (signups_paused); everyone who already has an account keeps signing in. Nobody with an account is ever refused because of a limit.
