Magic is a developer SDK which you can integrate into your application to enable passwordless authentication using magic links.
Magic enables the authentication process through following steps:
User login with their email address and a magic link is sent to the address through use of Magic SDK.
User clicks on that link for authenticating to the application.
Successful login message is shown up and user is securely logged in.
Thus with Magic SDK, you can enable blazing-fast, hardware-secured, passwordless login with a few lines of code. It is also plug-n-playable even if you already have an existing auth solution!
