Hello,
To my knowledge, emails are still being sent out and not everyone will receive it at the same time, please check junk/spam folders as sometimes it can get lost there 🙂 As every college is responsible for sending out accommodation info, the time and duration will differ but if you have not received anything, then you can reach out to the college.
As for usernames/passwords, they are still being sent out to students.
I hope this helps!
