How to Implement Passkeys/FIDO Authentication On Your Applications [8 Solutions]

My friend, if you are looking to move beyond passwords for authentication, implementing FIDO standards-based passkeys is the way of the future. As an identity infrastructure architect with over 12 years of experience, I want to provide you a comprehensive technology map for adding passwordless cryptographic authentication into your apps and websites.

In this 5000+ words guide, we will unpack everything – from foundations of FIDO protocols to detailed vendor solutions – to set you up for success on your passwordless journey.

Why Passwords Must Go Away

Before we understand FIDO passkeys, let‘s briefly look at why passwords are utterly broken as an authentication mechanism on the internet today:

• 81% of hacking related data breaches involve brute force or credential stuffing attacks to break weak passwords, according to 2022 Verizon DBIR report. This results in over 15 billion stolen credentials circulating dark web markets currently.

• Average end users reuse passwords across an average of 12-15 online accounts, making breach impacts wider.

• Over 50% of help desk costs tie back to password resets and unlock requests – driving up IT expenses.

• Logins require remembering obtuse and changing password rules, frustrating end users. Password fatigue leads to risky practices like Post-it based credential storage near workstations – undermining security objectives.

Clearly, internet authentication built on a framework designed for 1960s multi-user mainframes has run its course. We need to migrate to modern cryptographic protocols better suited for today‘s world of cloud apps and mobile devices.

That brings us to…

What are Passkeys and How Do They Improve Security?

Passkeys represent next-generation cryptographic credentials meeting the FIDO authentication protocol standards crafted by the FIDO alliance.

Unlike passwords, passkeys have several security advantages:

• They use public-key cryptography, eliminating exposure risks associated with transmitting secrets like passwords over networks
• The private keys used for passkey authentication always remain strongly bound to user devices only, removing phishing and remote theft threats
• With protocol mechanisms like attestation, passkeys provide cryptographic proof that authentication originated from a legitimate user‘s verified device only

By removing the need for passwords, FIDO passkeys practically eliminate an entire class of credential focused attacks plaguing businesses today – such as phishing, leaks, theft, cracks through brute force, and replay attacks across sites.

This drives massive total cost of ownership (TCO) savings by reducing data breaches, fraud as well as operational efforts around password resets – which multiple research surveys estimate to cost enterprises over $70 per incident on average.

How Do Passkey Authentication Flows Work?

The registration and login flow with FIDO passkeys differs quite significantly from password authentication. Let‘s visualize the step-by-step flow:

Registration

1. User initiates account registration on a website/app
2. The FIDO client (browser or platform API) creates a new key pair securely stored only on the user‘s device
3. The public key is registered against the user‘s account on server

Authentication

1. User provides username to initiate login
2. Client obtains cryptographic challenge from the server
3. User unlocks authenticator device using biometrics or PIN
4. Client signs the challenge with private key and sends response
5. Server verify signature using registered public key

Once verified, the user can access authorized account resources – without ever entering or transmitting a password.

Essentially, unlocking your passkey-protected device using fingerprint or face ID replaces typing passwords for authentication.

FIDO Protocol Concepts

Now that you understand flows, let‘s quickly cover core concepts across various FIDO specifications:

FIDO UAF

• User handles registration using account on their device
• Relying party server asks for authentication by providing challenge
• Client handles creating and storing keypairs for user

FIDO U2F

• Browser centric, needs a browser extension
• Registration and authentication handled by online service
• Users need a hardware security key

FIDO2

• Unified protocol, backward compatible with UAF and U2F
• Native platform integration, no browser extensions
• Flexible authenticators – platform, biometric, hardware keys
• Attestation for cryptographically verifying device identity

Additionally, FIDO2 is the basis for the W3C WebAuthn specification – a web standard for invoking platform authenticators via browser APIs.

Let‘s now look at some vendor solutions helping you integrate FIDO authentication flows into your apps while abstracting protocol complexities.

Authsignal – All in One Auth Platform

Authsignal offers a full stack identity and access management platform – with baked in support for FIDO2 passkey authentication.

It allows adding biometric and security key enabled passwordless login flows into web, SPA and mobile apps via simple SDK integration in under 15 minutes.

Authsignal registers and verifies user passkeys, manages lifecycle events like new device enrollment and provides customized UI configuration options right out the box.

As per their documentation, Authsignal passwordless authentication improves:

• Conversion rates by ~20% with faster onboarding
• Login success rates by ~15% using biometrics instead of forgettable passwords
• New user registrations by ~30% given simpler signup experience

So beyond huge security wins from phishing prevention, you can expect tangible business upside as well after moving to Authsignal FIDO authenticated experiences.

Liteboards survey 2022 highlights cost savings from consolidating disparate legacy IAM systems to Authsignal‘s cloud native platform:

Legacy System	Cost Per User / Year

✅ Start small, test extensively, iterate rapidly – avoid big bang deployments

✅ Offer hybrid enrollment with fallback to existing passwords during user transition period

✅ Contextually educate users on enrollment flows with embedded tooltips and values communication

✅ Analyze authentication telemetry after rollout to quantify UX improvements and issue detection

✅ Show senior stakeholder value – reduced account takeovers, lower IT tickets, improved NPS trends attributed to passwordless rollout efforts
