firebase - Using push() method to create new child location without unique key

Question

In my firebase web app when new users signup with their email i create a node under their email adress under the root ref

But the problem is using push() method to add every new user to the database every user is created with a unique key like below

-users

----ASFTU578FE

---------user: [email protected]

----FDWWE36S46

---------user: [email protected]

----WERSRTT23W

---------user: [email protected]

Now how can i access the path for a user since i dont know the unque key that will be created for every new user

Is there a way to push new user without a unique key but the key i know like user.displayName or user.email
