I want to get the date of creation of the user registration in the application, to compute a trial period. I thought about creating a cloud function to feed a variable with this value, which would be perfect for new cases, but it would not do anything for the almost 270 users in production. However, I saw that the panel already exists such a date and would like to get this data. How can I access this data?
You can capture this data using the firebase CLI with the command:
firebase auth:export account_file --format=file_format
where account_file is the name of the file where the data will be saved and file_format the file type, which can be either CSV or JSON. The results for JSON are something like this:
{"users": [...
{"localId": "key",
"email": "[email protected]",
"emailVerified": false,
"passwordHash": "hash==",
"salt": "salt==",
"lastSignedInAt": "1504893158000",
"createdAt": "1504558948000",
"providerUserInfo": []
}
...]}
You can use the Firebase Admin SDK to get the date. But you can not use it on android. I believe that for new users you do with metadata, and create a simple java program using the SDK and feed this database.
Just commenting, you can not use Android for two reasons:
If you add a SDK of this in an application to the general public, you'll empower them to manage your infrastructure.
The package names for both platforms are the same, and you would have conflicts on android.
The Admin SDK also has a version for node.js, so I think I can use it in cloud functions too (correct me if I'm wrong)
