Authentication

Before you start

Once you setup your Supabase project and you DB schema, you can start setting up authentication. To get started with authentication, you need to ensure the following:

  1. Correct authentication providers are activated in your Supabase project.
  2. Set up the default Redirect URLs in your Supabase dashboard.
  3. Learn how to manage the email templates in Supabase.

Authentication Providers

The following authentication methods are implemented in pro plan by the Supabase Auth service:

Passwordless email logins

Email logins using Magic Links or One-Time Passwords (OTPs)

Supabase Auth offers a variety of passwordless login options. These methods enable users to sign in without a password, either by clicking a confirmation link or entering a verification code.

Passwordless login can:

  • Enhance user experience by eliminating the need for users to create and remember a password.
  • Enhance security by minimizing the possibility of password-related security incidents.
  • Lessen support load related to password resets and other password-related procedures.

Magic links are a secure way to authenticate users without requiring them to remember a password. When a user signs in with their email address, Supabase sends them an email with a link that they can click to sign in. This link is valid for a short period of time and can only be used once.

Supabase Auth offers two passwordless login methods that use the user’s email address:

Email authentication methods, including Magic Links, are enabled by default.
