How to verify user's current password when changing password on Firebase 3?

I want the user to insert the current password and the new one when updating his password.

I've searched Firebase documentation and didn't find a way to verify the user's current password.

Does anyone know if this is possible?

You will be able to achieve it using reauthenticate before changing the password.

let user = FIRAuth.auth()?.currentUser
let credential = FIREmailPasswordAuthProvider.credentialWithEmail(email, password: currentPassword)    

user?.reauthenticateWithCredential(credential, completion: { (error) in
    if error != nil{
        self.displayAlertMessage("Error reauthenticating user")
        //change to new password

Just for add more information, here you can find how to set the credential object for whatever provider you are using.
