We recommend having one Luma account per person. That ensures you can see all of your upcoming events in one place without switching between accounts.
You can link your Luma accounts in your Luma Settings page.
When you link an additional email, all invites sent to that email will be linked to your primary Luma account.
If you already have an existing Luma account with an email you'd like to link, you'll need to log into that account and delete it. Then you'll be able to link it.
We aren't able to merge two Luma accounts on the backend.
