Create your own Passwordless Authentication Server | NodeJS & ExpressJS

Показать описание


A great way to streamline your login process is to ditch the email/password system and use Passwordless Authentication/Magic Links.
The user just enters their email address, you send a link to their email, they click the link, they log in.

This tutorial uses JWT or JSON Web Tokens to accomplish the secure exchange of permissions.
We build our server using NodeJS and Express.

Hey man, awesome video :). Thank you for also sort of 'simulating' what we would have to do with the database instead of saying something generic. I'll probably watch this vid a few more times and implement it.

Cool, this idea, but I would like to think of something where I could validate the user only once through their email, and then not need to validate more, unless they lose the local settings, or it is valid only once and I leave the validation locally... I want to make a simple pwa app to order gas or water, but I don't want another person who knows the person's e-mail to impersonate him to order something... .

I don't know how I would do it, I don't know how to understand, is that if a person asks for a gas, he is using his own phone, so he is himself in theory... I need to validate the same thing
but only with email
