Well... I was able to set up a new password & an access code which I have not been able to do since he set about making all the changes. So either he is getting ready to get a new account for himself or he is giving me access to reassure.
Give him 24 hours and see if he tells you what's going on. I suspect he's going about giving you access to an account he no longer cares if you see or not. Whether or not that's because he's agreeing to no more OW contact, or whether he's moving that contact to another channel, remains to be seen.
