Hello! I'm considering using FusionAuth for my products but there's a "must-have" I haven't figured out how to accomplish.
Within my target audience, it's very common for people to have multiple email addresses and using different emails on different times. As such, it's very commont that one person ends up with multiple accounts in my app, and we have to manually merge both accounts into a single one.
I need a way for the users themselves to merge their accounts. For instance, we could send a code for email1 and another code for email2, and if the user types in both codes, we know it's one person and then we can merge the accounts.
I know it's possible to do that with both AWS Cognito and Auth0, but I couldn't figure out (from reading the docs) if it's possible with FusionAuth.
Can someone advise on that, please?
