How does Logto passwordless work

Email and verification code is a secure, user-friendly method that eliminate the need to remember passwords. Here is how the user flow for this process typically unfolds:

Step 1: User enter email or phone number

The journey begins when a user lands on the sign-in/up page. Here, they are prompted to enter their email address.

Step 2: Code generation and delivery

Once the email is submitted, the system generates a unique code. This verification code is then sent straight to the user inbox.

Step 3: Code entered, access granted

Upon enter the code to the interface, the application receives the access token. This token serves as proof of identity and is used to authenticate the user without requiring a password.

Frequently asked questions

How does passwordless authentication differ from email & SMS verification codes?

In short, email & SMS verification codes is a subset of passwordless sign-in. Passwordless authentication is a method of logging into an account without using a password. Instead, it relies on alternative forms of verification such as biometrics, physical tokens, or one-time codes sent through a communication channel like email or SMS.

Email and SMS verification codes require the user to enter a code sent to their email or phone number in order to authenticate their identity. It can work alone as an authentication factor or be pair with setting a password. Some times social sign in can also be considered as passwordless sign-in. You can check "MFA" & "Social sign-in" to learn more.
