At this time, Runn uses emails as unique identifiers. As a consequence, you aren't able to update emails addresses for users- but you will need to do it for resources so that can log in with their new emails and still see their allocations to add in time. This is a 2 step process:
Updating SSO and Users
1. Turn off SSO only login - you can turn it back on once you've set up the new SSO.
3. Go to the Manage> Users and add your users with NEW email addresses:
You will need to assign the permissions again to the new emails.
You can also use the CSV tool to bulk invite users with the new email addresses.
4. Once they have accepted- they will now have access using the new SSO. So you can now remove their old email log-ins.
