For users who have more than 1 email address it would be useful to have 1 user associated with multiple email addresses.
As described, currently users are associated with a single email address. Based on community feedback and current priorities, we are unlikely to make changes in this area. We hope you can understand.
This would be a huge help for integration support. For example, I rely heavily on integration with Azure DevOps portals which all use an SSO email, while the SSO that those same users use to sign into Aha uses a different email.
The result is that I have two Aha Users for every single actual user. One is to track who tasks are assigned to through integrations, the other is to allow those users Reviewer access to Aha. It is a source of constant confusion between the two as they typically have the same user name.
