How To Add Biometric Passwordless Authentication to Any Web App [Discover OnzAuth Solution]

We’ve certainly come a long way in terms of developing methods of securing our data, with the first line of defense being the use of unique passwords to prevent unwanted intrusions into our privacy. But here’s the catch.

Passwords are becoming obsolete, and not just because it is difficult to remember all of those upper and lower-case letter combinations. People simply do not believe they are secure enough anymore.

Fortunately, there are other authentication methods that are just as, if not more, effective than passwords. Think of stuff like biometric authentication like fingerprint and face ID, magic links, etc. If you own a website, protecting your users’ privacy should be one of your top priorities, and using these methods will get you there.

But how do you go about incorporating these authentication steps into your website? Let’s find out by taking a look at OnzAuth, our current favorite passwordless solution!


Set Up Biometric Authentication

OnzAuth has you covered if you’re looking for a quick and easy way to add a new authentication method to your website. You can set up biometric or magic link login methods for your users in minutes, whether as your primary login method or as MFA.

It’s ridiculously simple, thanks to OnzAuth’s user-friendly SDK. This powerful tool can be integrated into your website using any programming language of your choice. It’s worth noting that OnzAuth was built using modern browser standards such as W3C WebAuthn and oAuth 2.0, so you don’t have to worry about it not working across all browsers.

How Does OnzAuth Work?

If you’re scratching your head, wondering how this works, sit tight because you’re about to learn something today. When a user registers on your website, OnzAuth generates both a public and a private key pair.

The public key then identifies the user in the same way it would identify a username and compares it to the biometric data stored on the user’s device (private key). If the public and private keys match, the verification process is complete, and the user can proceed with the login.

It’s quick, safe, and increases conversion rates because users are more likely to visit and stay on websites where they don’t have to spend much time logging on.

Use for Primary Authentication and MFA

What authentication options does OnzAuth provide? Aside from face ID and fingerprint scanning (depending on the user’s device), FIDO2 keys and magic links can be used as primary authentication methods.

If you only want to add another step to the authentication process, OnzAuth also works well as MFA. Don’t worry. OnzAuth does not store any user’s biometric data, as this is only available on the user’s device.

Pricing and Plans

Now that we’ve covered what OnzAuth is, you might be wondering how much it costs. For a one-time payment of $49, you get lifetime access to OnzAuth-Passwordless WebAuthN and Magic Link Authentication Plan.

This includes passwordless authentication for your users, activity logs, custom UI, and more. All future releases, including User Exports, custom claims, analytics, and more, will be available without having to pay anything extra.


OnzAuth is currently only available on Webflow, as the WordPress plugin is still being developed. If you want to integrate a secure and simple authentication method into your website, tools like OnzAuth are designed to assist you.

It’s time to ditch passwords altogether, as so many new authentication methods continue to prove to be more reliable and easier to use. Nobody wants to waste time remembering and entering passwords anymore, so now is the time to embrace this new authentication trend, which we believe will soon become the norm.

Hop on the bandwagon, and reap the conversion rate benefits these means of authentication offer! You won’t be disappointed.
