What Is Passwordless Authentication?
Passwordless authentication skips using a password for registration or login. Instead, user authentication is confirmed either with a one-time SMS verification code sent to the user’s phone or a one-time link to their email address.
Why Use Passwordless Authentication?
Seamless login and registration process for your users.
Keeps access to your app secure, because the user will not reuse passwords or resort to easily guessed passwords (such as “password”).
Avoids taxing your users with the need to create and remember unique passwords
