Firebase read rules

i can't read data from firebase using this rules
{
"rules": {
"users": {
".read": "auth !=null", //here i want to read all users data only after authentication
"$uid": {
".write": "$uid === auth.uid" //for writing uid is used but for reading all users data should be
displayed how is that possible without uid

  }
}
