Sending Login Link to Users by email

[ephraimduncan]

I have an application with a set of email for all the users who will be able to use it. I want to

1. Generate a Login Link for each user
2. Send it to their mail so that when they click on it, they will just be logged in.

My question is, how do I use Next-Auth to generate the login details for each user.

Magic Link is when a user will have to enter their mail first on the app and the login link is sent to them. I already have the users so how do I generate the link myself and send it to them straight away without coming to the app in the first place?
