Force signup with certain email address in Lock?

Hello! I’m using Lock to sign up users partway through our onboarding flow. At that point, the user has already provided an email address in a previous (non-Auth0) form. Is there a way to force the user to sign up with this address? I’m interested in knowing this for the conventional email/password fields, Google authentication, and potentially a one-time code for passwordless logins. Thanks!

Hi @tlhinman,

I think you should be able to prefill with this option:

But as far as forcing use of a specific email, I don’t think you are able to do this and can’t find any requests for it. If it is a feature you are interested in I would highly recommend submitting to feedback. It is how the product team engages with customers and monitors demand for features.
