By default, if no password is provided, the user will be sent a "magic link" to their email address, which they can click to open your application with a valid session. By default, a given user can only request a Magic Link once every 60 seconds.
|
|
|
|
## Overview
|
|
|
|
Setting up Magic Link logins for your Supabase application.
|
|
|
|
- Add Magic Link authenticator to your [Supabase Project](https://app.supabase.com)
|
|
- Add the login code to your application - [Javascript](https://github.com/supabase/supabase-js) | [Dart](https://github.com/supabase/supabase-dart)
|
|
|
|
## Add Magic Link into your Supabase Project
|
|
|
|
- Go to your [Supabase Project Dashboard](https://app.supabase.com)
|
|
- In the left sidebar, click the `Authentication` icon (near the top)
|
|
- Click `Settings` from the list to go to the `Authentication Settings` page
|
|
- Enter the final (hosted) URL of your app under `Site URL` (this is important)
|
|
- Under `Email Auth` turn `Enable Email Signup` to ON
|
|
- Click `Save`
|
|
|
|
