Multiple Email accounts logging into the same application

I have a user that wants to use multiple email accounts to log into the same application, Zoom in this case.

Is it possible for my user to have multiple emails,, in the same Okta account and all have the ability to log into 1 account in Zoom, in this example?

Yes but likely you would need to use an Incognito/Private browser to ensure the session cookie is not reused for each user context
