Answer 1

You can use a CSS attribute = value selector of [tabindex='3']. This targets the login button by its tabindex attribute whose value is 3.
HTMLDoc.querySelector("[tabindex='3']").Click
Whole thing:
Option Explicit
Public Sub AttemptLogin()
Dim IE As New InternetExplorer
With IE
.Visible = True
.Navigate2 "https://willemendrees.nl/fn/login/"
While .Busy Or .readyState < 4: DoEvents: Wend
With .document
With .querySelector("#id_username")
.Focus
.Value = "amsterdam#willemendrees.nl"
End With
With .querySelector("#id_password")
.Focus
.Value = "***"
End With
.querySelector("[tabindex='3']").Click
End With
While .Busy Or .readyState < 4: DoEvents: Wend
Stop '<== Delete me later
.Quit
End With
End Sub

Answer 2

It seems there are two form elements on that html page and the login is the second. Identify, then submit the form.
HTMLDoc.all.id_username.Value = "amsterdam#willemendrees.nl"
HTMLDoc.all.id_password.Value = "*****"
HTMLDoc.getelementsbytagname("form")(1).submit
The index number of a collection of elements is zero-based.
