A router may be ~200, but I imagine monthly plans for unlimited are over 100/month from a traditional cell provider.

This seems very expensive. How do you set up the monthly plan more efficiently?

Facebook does not guarantee an email address, either. (Just went through this process with Apple/Google/Facebook/Email auth - even using Firebase Auth library - surprising how many edge cases there were).

Recently went through the same debacle. Our hope was that we could solely rely on Magic Link instead of email/password ... but it turns out many users don't really understand it [1]. So your options are:

1) Email/Password Sign In

2) Bite the bullet and add Apple / the "full auth stack" (FB/Google/etc.) & deal with account linking issues.
