Firebase and authentication pricing

1
votes

I'm totally new to working with Firebase and have two simple questions about the pricing because I want to make sure I'm not exceeding my own price limit later on.

  1. On the Firebase-Website it says in terms of authentication you're being charged per successful verification, does that mean I only have to pay every time a new user registers or do I also have to pay when an existing user is logging in or I'm retrieving data from a user profile?

  2. Regarding the Firebase Realtime Database it says you're being charged depending on the amount of stored and downloaded data, so does that mean saving data to the Realtime Database is completely free and that I principally wouldn't have to worry about saving too many times?

(both are probably self-explaining, but I don't want to do any mistakes)

Thanks in advance :)

  1. Per verification means, per successful login
  2. For the database, you have two options, Realtime Database (old) and Firestore (new). Realtime database is charged based on bandwidth and storage, while Firestore charges based on operations (daily 20k write, 50k read and 20k delete free of charges)

For those who still come across this question, here's a proper answer to my question:

  1. The authentication pricing refers only to phone authentication since all other authentication services are free anyway. Which means, if you want to verify a user via SMS you will be charged for each verification after you have exceeded the monthly limit of 10k verifications.

  2. This question has already been answered here.
