7 Passwordless Approaches for B2C Websites

If we all only trusted each other, passwords wouldn't exist. But some people claim to be a person they're not and that's unfortunately a threat. Passwords have been used for centuries to help us prove that we are who we claim to be.

But passwords are problematic. They are hard to remember, and they don't work well. Passwords can be guessed or leaked. B2C websites and apps realize this security threat and try to overcome it by requiring users to create complicated passwords and then replace them often. As a result, people reuse passwords across multiple websites and write them down, leaving themselves and the business vulnerable.

But today's technology allows for better authentication, without passwords. It's time to move on and join the cutting edge.

I've listed below the different types of passwordless authentication methods that exist in the market. These methods can stand alone or be part of a multi-factor authentication process (2FA or MFA).

Authentication based on real-time communication

This is a common password alternative. Since a username is typically the user's email address or phone number, the website can authenticate by sending a communication to the user and asking them to respond.

1. OTP (One-Time Password)

A code sent via SMS or email that expires after use.

2. Magic Links

A unique link sent to email that logs the user in when clicked.

3. Biometric Authentication

Using fingerprint, face, or voice recognition.

4. Hardware Tokens

Physical devices that generate authentication codes.

5. Push Notifications

Approve login requests from a trusted device.

6. QR Code Authentication

Scan a QR code with an authenticated mobile app.

7. Passkeys

The newest and most seamless approach using FIDO2 standards.
