title: Register users with magic link in firebase?
body: <p>I'm working on a product being targeted to companies with employees. We get a collection of employee emails to which we need to register them for an account on our firebase platform.</p>
  
  <p>Ideally what I'd like to do is use this data to create all the user accounts on firebase then email them all a unique magic key to verify their registration and let them input a password.</p>
  
  <p>Unfortunately I'm a bit stuck on making the magic link custom tailored to the users email. Looking at firebases dynamic link creator it doesn't look like there's a way to create a dynamic magic link where I can input something unique about the user account to later identify them after they click on it to give them the correct onboarding platform.</p>
  
  <p>Any ideas how I could accomplish this?</p>
