How do I do it?
The email login option using IA account credentials is not working.
I thought it was through IA account IDP.

How do I do it?
Well, I was logged in, and then I had to try to experiment, and now I can't log in either
I'll see who I need to talk to internally; this might be related to some rollouts of our new account system internally.
Being able to log in to the Ideas Portal sounds like a great idea. Someone should add it to the Ideas Portal… oh wait…
Bumping this, as it's still an issue this morning.
Works now!
I cannot login either
I've tried logging out and logging back in, and it works fine on my end. IA made some account changes recently, so maybe try logging in through the main site and then try again.
