Passwordless authentication with OTP, magic link, and passkey
Eliminate password risks while accelerating onboarding. Use email / SMS verification codes, one-click magic links, and phishing-proof passkeys for secure, frictionless sign-in experience.
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.
