3 Steps to Phoenix Authentication

Phoenix Auth Has never been so simple

I already written how to add social authentication in phoenix

But for email password authenitcation Its amazingly simple now.

Authentication

open mix.exs and add deps.

{:phx_gen_auth, “~> 0.6.0”}

Then run,

mix phx.gen.auth Accounts User users

mix ecto.migrate

and thats it. We have full fledge authentication system.

run the server and try it in the browser

http://localhost:4000/users/log_in

you should see login page.

Bonus:

To guard a routes we can pass scope through the require_authenticated_user plug. It is already in our route file generate by phx_gen_auth

pipe_through [:browser, :require_authenticated_user]

To guard a specific action in controller

import TailwindWeb.UserAuth, only: [require_authenticated_user: 2]
plug :require_authenticated_user when action in [:my_rooms, :new, :edit, :delete]
