Does auth0 charge if we have a big number of inactive user accounts(e.g. 1M+) created thru the authentication api
No. You pay for “Monthly Active Users” (MAUs), meaning users who actually log in. If, on average, you have 100 users (any 100 users) who log in per month, then you pay for 100 MAUs, no matter how many users you have.
Thanks for helping on this one Mark!
