Magic.Link

Magic is a user authentication and private key management solution for Web3 and Web2. Magic links are a great way to create a smooth login experience for your users.

Magic links are a form of passwordless login. Instead of entering your login credentials to sign in, such as an email address + password, you're instead sent a URL with an embedded token via your email address.

Once you click on the link that's sent to your email, you are then re-directed back to the originating site with a successful sign-in.
