In today's world we have to have millions of accounts to different services all using unique passwords. Most security breaches happen due to human error. It is really hard to remember millions of passwords in your head. Passwordless login makes your account much more secure.
With passwordless authentication, you don’t have to trust websites with a password. When you attempt to login, you provide an email address. We then send a secure email to the address associated with your account, and the email contains a secure, single-use magic link to enter your account. The magic link includes a unique login token that we verify, swapping it for a long-time validation token.
