{
"rules": {
"users": {
"$user_id": {
".read": "$user_id === auth.uid",
".write": "$user_id === auth.uid"
}
}
}
}

This example ensures that users can only access their own data by comparing their user ID with the authenticated user’s ID.

Important Considerations

Make sure to test your security rules thoroughly before deploying to production to avoid unintended access or data loss.
