The same way you canemulate Firestore databasefor your development you can also emulate Firebase Auth users. This is accomplished through theusersfield inside theconfiguration file.
You have two options on how to set the emulated users:
Specify users directly with JSON:
users:
-id:user-id-1
# The 'data' field takes a JSON string
data:'{"email": ""}'
Copy users from your production Firebase Auth users
