JustAuthenticateMe: Simple passwordless authentication for your next web app.

Hello Product Hunt! I'm Grant, first-time founder and creator of JustAuthenticateMe. JustAuthenticateMe uses itself for authentication, so all you have to do to try it out is sign up! ;) I created JustAuthenticateMe after dealing with the complexity of using other authentication-as-a-service platforms out there. Some of the problems I dealt with are: 1. They all use passwords. Passwords are the status quo, but are an unnecessary evil. Most people don't use a password manager and either frequently use the "Forgot your password" feature of apps, or reuse passwords - putting the security of their accounts at risk. 2. They all keep a database of your users. This is necessary when using passwords, but creates an extra burden on the app developer to make sure their app's user database doesn't get out of sync with the authentication provider's database. 3. The web javascript libraries were unnecessarily large - like 10-20Kb large. This was by far the largest dependency in the last web app I made and I knew I could do better for my user experience. JustAuthenticateMe doesn't have any of the above problems. It uses email-based magic links for authentication, doesn't keep a database of your users, and has a tiny ~1Kb web JS library. It uses modern cryptographic algorithms to make sure your app is secure. JustAuthenticateMe is free for up to 300 logins per month, which should be plenty to get your app developed and off the ground, but just for Product Hunt launch day, we are DOUBLING the free tier, so if you sign up today you will get 600 logins per month for free! Please leave comments with your questions and thoughts about email based authentication vs passwords. I hope you all will consider JustAuthenticateMe when creating your next product! :) Happy Authenticating, Grant

This looks awesome! Will definitely be trying it out.

@perry_ogwuche Thanks! Let me know if you have any questions while integrating it

Very interesting. Could you give a bit more detail on how it works without a password? Does the user have to download something or sign up somewhere? Does it use browser/computer identifying metadata?

@_steven_ It uses magic links in emails to verify that user's have access to their email account. So the flow is: 1. User enters their email address. 2. User receives an email with a one time use link. 3. User clicks the link and JustAuthenticateMe creates an ID token for the User. 4. JustAuthenticateMe redirects back to your app with the User's ID token. This model essentially means that JustAuthenticateMe authentication is as secure as the User's email account. JustAuthenticateMe also provides refresh tokens so that your users don't have to go through the entire email link procedure every single time they want to use your app.
