What is Passwordless Authentication?

A passwordless authentication system allows users to verify their identity without inputting traditional passwords. Instead, it employs alternatives like:

• Email magic links: A one-time clickable link sent via email.
• OTPs (One-Time Passcodes): Temporary codes sent to users.
• Social logins: Using existing profiles on platforms like Facebook or Google to sign in.
• Authenticator apps: Software that generates time-sensitive codes, acting as a secure passwordless authenticator. This approach enhances security by minimizing the risks associated with password breaches, making it an innovative solution for modern digital platforms.

As cyber threats evolve, the traditional password has become more vulnerable. This vulnerability has given rise to password-free systems which provide a more fortified barrier against breaches.

• Enhanced Security: Reduces the chances of phishing attacks, brute force, and other common password-related breaches.
• Improved User Experience: Users no longer need to remember complex passwords, leading to faster and smoother logins.
• Lower Support Costs: Reduces the volume of 'forgot password' support requests.

• Email Magic Link: A simple yet effective method. Users enter their email, receive a link, click it, and they're in.
• OTPs: Often sent via SMS or email, these codes are valid for one session or a short duration.
• Social Logins: By integrating with platforms like Facebook or Google, users can sign in with an existing profile.
• Authenticator Apps: These apps, like Google Authenticator, generate codes synchronized with the server, ensuring only the user with the app can log in. They represent a popular form of passwordless authentication using an authenticator device or application. ‍

The primary advantage is enhanced security and better user experience. By removing the traditional password, the risks of phishing, brute force attacks, and other password-related breaches are minimized. Besides, users have a better experience as they do not need to come up with and manage passwords

An email magic link is a unique, one-time clickable link sent to a user's email address. Once clicked, it authenticates the user, granting them access.

Not exactly. While OTPs can be a form of 2FA, passwordless OTPs serve as the primary method of authentication rather than a second layer.

Social logins leverage the security infrastructure of established platforms, making them quite secure. However, they're as secure as the associated platform's security measures.
