This feature is useful if you have an existing email list and want to send each user a personalized sign-up link that will pre-fill the login screen.
It requires you to install the Magic Link add-on. Users will now be able to log in using their name and email address, not their name and phone number.
Once installed, you can create add some parameters to the URL of your channel, which will pre-fill the name and email fields of the sign up form.
You can then personalize these fields using your email software.
Users will still have to request the magic link each time they want to sign in but do not have to fill out the login form.
