# Magic Links Tutorial
2023-05-10 15:48:27 +12:00
This is a quick tutorial to get you up and running on Magic Links.
This assumes you've set up `ash_authentication` and [password reset ](https://ash-hq.org/docs/guides/ash_authentication_phoenix/latest/tutorials/getting-started-with-ash-authentication-phoenix ) in your Phoenix project.
## Add the Magic Link Strategy to the User resource
```elixir
# ...
strategies do
password :password do
identity_field(:email)
resettable do
sender(Example.Accounts.User.Senders.SendPasswordResetEmail)
end
end
# add these lines -->
magic_link do
identity_field :email
sender(Example.Accounts.User.Senders.SendMagicLink)
end
# < -- add these lines
end
# ...
```
## Create and email sender and email template
Inside `/lib/example/accounts/user/senders/send_magic_link.ex`
```elixir
defmodule Example.Accounts.User.Senders.SendMagicLink do
@moduledoc """
Sends a magic link
"""
use AshAuthentication.Sender
use ExampleWeb, :verified_routes
@impl AshAuthentication.Sender
def send(user, token, _) do
Example.Accounts.Emails.deliver_magic_link(
user,
url(~p"/auth/user/magic_link/?token=#{token}")
)
end
end
```
Inside `/lib/example/accounts/emails.ex`
```elixir
# ...
def deliver_magic_link(user, url) do
if !url do
raise "Cannot deliver reset instructions without a url"
end
deliver(user.email, "Magic Link", """
< html >
< p >
Hi #{user.email},
< / p >
< p >
< a href = "#{url}" > Click here< / a > to login.
< / p >
< html >
""")
end
# ...
```
