Extract Created date and last login from firebase authentication using Python

Question

Currently my python code gets the user id and email of all users from firebase authentication using the firebase admin SDK, however I am unable find the correct syntax to extract the user metadata such as the created and last login date/time (which according to the documentation is in milliseconds). There are a few documentation that shows ways to do this, but it is not working for me.

My code:

from firebase_admin import credentials
from firebase_admin import auth

cred=credentials.Certificate('firebasesdk.json')
firebase_admin.initialize_app(cred, {
    "databaseURL": "myurl",
})

page = auth.list_users()
    while page:
        for user in page.users:
            print('User email: ' + user.email)
            print('User id: ' + user.uid)

I tried using user.metadata.creationTimeand user.madata.getLastSignInTimestamp and but it does not work with python. I was looking through this post regarding this issue.

Answer 1

It looks like the ExportedUsers result for list_users does not include the metadata for the users. In that case you’ll need to call get_user(...) for each UID in the result to get the full UserRecord, and then find the timestamps in the metadata.

The correct syntax is user.metadata.creation_timestamp and user.metadata.last_sign_in_timestamp. See API reference: https://firebase.google.com/docs/reference/admin/python/firebase_admin.auth#firebase_admin.auth.UserMetadata

To get creationTime and getLastSignInTimeStamp, you can access creation_timestamp and last_sign_in_timestamp from the user_metadata field. For example

from firebase_admin import auth

page = auth.list_users()
    while page:
        for user in page.users:
            print('User creation time: ' + user.user_metadata.creation_timestamp)
            print('User last sign in time: ' + user.user_metadata.last_sign_in_timestamp)
        page = page.get_next_page()

or

from firebase_admin import auth

for user in auth.list_users().iterate_all():
    print('User creation time: ' + user.user_metadata.creation_timestamp)
    print('User last sign in time: ' + user.user_metadata.last_sign_in_timestamp)

Each timestamp is an integer representing milliseconds since the epoch.

More info:

user is a ExportedUserRecord which inherits from UserRecord

user_metadata is UserMetadata
