Hi Peter,
Ah, I got the impression they were talking about the portal but perhaps other logins will keep things active. As you say, there used to be regular disconnections so plenty of logins - it's a bit odd though that an open connection doesn't keep your account active.
Here's exactly what I got from support
"Once any account is activated there
is a requirement to log in to the account via the
portal once every 28 days or the account will
become deactivated and require re-creation. This
is a requirement that has always been there.
Our automated inactive account
deletion process on the updated system had issues
until recently, which was causing the platform to
be overrun by inactive accounts preventing other
users from creating an account. That issue has
now been rectified. If you haven't logged into
the portal itself in the past 28 days, this will
most likely be why the account was
deactivated/deleted."
It turns out my login issues after recreating the account was because there's no response difference between "no account" / "wrong password" / "too many failed attempts, you're blocked" so I just ended up on the blocked list that needed to time out. In the end it was quicker and easier to setup an account with a new email address then I had things up and running in no time.
I really hope system logins satisfy the requirement, I can't stir the enthusiasm to login to the portal every 28 days and the new login is slightly fancy making it non-trivial to have a script to do the job for me.
