Invicti Web Application Security Scanner – the only solution that delivers automatic verification of vulnerabilities with Proof-Based Scanning™.

As an online business owner, there are many things you have to take care of to secure your application, provide better authentication, a nice user experience, and more.

If you offer user authentication on your web applications, then there are few options you have. Traditionally, one goes for username and password authentication.

But there is a problem…

Can you count how many passwords you own?

You’re puzzled, right?

It seems like I just asked you some high-level mathematics.

Yes, it can be that hard.

It’s because you might have hundreds of passwords for accessing so many online solutions you utilize in your business or for your website. From emails and productivity trackers to project management, CRM, security solutions, you have passwords for each one of them.

Plus, you are advised not to use the same password in all the applications.

So, it becomes tough to remember each of them. And if you use a passwords manager, there’s still the likelihood of attacks. In case your passwords get hacked, all your passwords could be compromised.

You can’t imagine how scary it may turn out to be for your business!

So, what’s the solution?

Don’t worry; there’s a world beyond passwords.

And this world is – passwordless authentication.

That’s right!

As a developer, website owner – you can implement passwordless authentication, so your users no longer have to remember passwords and think about losing it or getting it stolen. And that’s the goal of this article to introduce you to this world, along with some of the best solution providers out there for this.

What is passwordless authentication?

Passwordless authentication is a system that swaps traditional password usage with more safe and secure factors. These high-level security methods might include a fingerprint, magic link, secret token, etc. that’s delivered via a text message or email.

It eliminates the need to generate a password to gain access to the systems. And this is good for your users as they won’t find any hassle while using a website or application developed by you.

The benefits of passwordless authentication are:

  • Enhanced experience: Whether it’s accessing the business emails, fingerprint scanning, or verification on an application, the users are not required to memorize their password credentials anymore, which is a true delight you can offer to your customers. It also leads to a great screen-time experience.
  • Stronger security: Passwords that are user-controlled are highly vulnerable to attacks like corporate account takeovers (CATOs), credential stuffing, brute-force attacks, etc. So, when there would be no passwords to exploit, users won’t get into any trouble while using your applications.
  • Increased convenience: Why go for a complex password that users need to keep track of all the time if they can have efficient options out there through passwordless authentication. Give your users extra convenience while gaining access or getting information anywhere and anytime they want.

Types of Passwordless Authentication

  • Email – where the users need to enter their email address to get a magic link or unique code to log-in
  • SMS – entering a phone number is required to get a unique one-time code to log-in.
  • Biometric – where fingerprint scanning, iris scanning, or face-scanning takes place to get access

There are so many services and APIs available where you can leverage passwordless authentication and integrate it into your applications instead of building an in-house solution. They are cost-friendly, save your development time, and bring you great security by just paying some nominal fee.

To your surprise, some of them are also available for FREE!

How does it help?

Passwordless authentication leverages technologies like digital certificates. It includes cryptographic key pairings.

The steps for the same are as follows:

  • A private key gets stored on a user’s local device and then linked to a type of authentication factor such as face recognition, fingerprint, or unique PIN.
  • Meanwhile, the public key moves to that application or website to which the user wants to access

So, if you have made up your mind to use passwordless in your applications, you have made a good decision.

Let’s now look at some of the best solutions that give you the power of this passwordless authentication technology along with the comprehensive set of features and security.
