I have created an application and implemented Firebase (Auth, Analytics, Remote Config, Crash Reporting) with it.
Now i need to change the Firebase account because in my collaborator account we will implement Realtime Database with BLAZE plan. (we need more than 100 concurrent connections to db)
Follow the below steps, to switch firebase account
Go to your firebase console, and select the project you want to shift
Select the icon besides the project name on top right.
Select Permissions from the flyout.
You've reached the IAM & Admin page of firebase.
Click on +Add button on top.
Enter the email ID of the account to transfer the project to.
In the dropdown, Select a role > Project > Owner. Click add Check mail in the email added above.
Accept the invite, and go to IAM & Admin page of the transferred project.
Use remove button to delete the previous user
Hope this helps.
