Marketo Sales Connect login password expiry

We have an option in Marketo to customize the password expiry duration in Admin > Login Settings. You can then click edit on Security Settings and change the Expiration, but there is no such option available for Tout (marketo sales engage) customers.

I see a lot of customers who need to change the password every three months in Tout wish to have a single login for both Marketo and Tout or at least have the option of customizing the password expiry duration in Tout.
