How to prompt for password after lost password link has been pressed

When a user clicks on the lost password reset link, meteor proceeds to

In my case

Accounts.onResetPasswordLink(function (token, done) {
  Accounts.resetPassword(token, "dummy") 
  done()
})

My problem is that I don’t know what I have to do to show the password prompt before doing Account.resetPassword(). The best I have been able to do is to flag in Session that a password change is needed and use “dummy” as the current password for that change

Accounts.onResetPasswordLink(function (token, done) {
  // I want a password prompt here
  Accounts.resetPassword(token, "dummy") 
  Session.set("password_change_needed", true) // <- flag
  done()
})

then an autorun monitors the “passwod_change_needed” flag and routes to the password change template in which I change the dummy password for a new one.

Template.password_change_prompt.events({
   'click button.sumbit' : () => Accounts.changePassword("dummy", new_password)
})

That’s not save because there is a moment during which the password is set to “dummy”.
