It depends. To deploy the Auth to Firebase you need to activate the Blaze plan for Google Cloud, which is pay-as-you-go. You pay only what you are consuming as resources on the cloud. Up to 50k montly active users should be free, yes, above 50k users you will have to pay. As far as I remember is something like 5 cents per user.
