Authentication with Passkeys: A Comprehensive Guide for CIAM

Understanding Passkeys and Their Role in CIAM

Imagine a world without the frustration of forgotten passwords and the constant threat of phishing attacks. Passkeys are making this vision a reality, offering a more secure and user-friendly authentication method for Customer Identity and Access Management (CIAM). Let's explore how passkeys are transforming digital identity.

Passkeys are a FIDO-based authentication method that replaces traditional passwords. Instead of typing in a password, users verify their identity using device unlock methods, such as:

• Biometrics: Fingerprint or facial recognition
• PIN: Personal Identification Number
• Pattern: A specific swipe pattern

According to the FIDO Alliance, passkeys are phishing resistant and secure by design, reducing cybercriminal attacks.

Unlike passwords, passkeys are tied to a user's account on a specific website or application. This means there are no shared secrets that can be stolen or reused across different sites.

CIAM focuses specifically on managing customer identities. It emphasizes user experience, ease of onboarding, and secure access for external users. Passkeys are a natural fit for CIAM because they:

• Enhance Customer Onboarding: Streamline the registration process, making it faster and easier for new customers to create accounts.
• Reduce Friction: Simplify the login experience, eliminating the need for users to remember and enter complex passwords.
• Improve Security and Compliance: Provide a higher level of security compared to passwords, helping organizations comply with data privacy regulations.

Implementing passkeys in a CIAM environment offers several key advantages.

• Enhanced Security: Passkeys are resistant to phishing and credential stuffing attacks, protecting customer accounts from unauthorized access.
• Improved User Experience: Passkeys provide a faster and simpler sign-in experience, boosting customer satisfaction and engagement.
• Reduced Costs: By reducing password reset requests and customer support inquiries, passkeys can significantly lower operational costs.

As passkey adoption grows, organizations can expect to see improvements in security, user experience, and cost savings. In the next section, we'll examine the technical aspects of passkeys and how they work.

Implementing Passkeys in Your CIAM System

Ready to ditch passwords for good? Let's dive into how you can implement passkeys within your CIAM system, making authentication smoother and more secure.

Implementing passkeys involves several technical and procedural steps. You'll need to consider compatibility, user enrollment, and account recovery to ensure a seamless transition.

• FIDO2/WebAuthn compatibility: Your CIAM platform must support the FIDO2 and WebAuthn standards. These standards provide the framework for secure passkey creation and authentication.
• Device and browser support: Passkeys rely on device-level authentication. Ensure your CIAM system supports a wide range of devices and browsers, including the latest versions of iOS, Android, Chrome, Safari, and Firefox.
• Integration with existing identity providers: Passkeys should integrate seamlessly with your existing identity infrastructure. You'll want to ensure compatibility with your current identity providers and directory services for a smooth transition.

1. Enabling passkeys in your CIAM platform:
   • Navigate to the authentication settings in your CIAM platform.
   • Locate the passkey configuration options.
   • Enable passkeys for your desired user groups.
2. User enrollment process:
   • Prompt users to create a passkey during registration or login.
   • Guide them through the process of registering their device with the CIAM system.
   • Ensure the enrollment process is user-friendly and intuitive.
3. Account recovery mechanisms:
   • Provide alternative account recovery options for users who lose access to their devices. This might include email verification or security questions.
   • Clearly communicate the account recovery process to users during enrollment.

• Leveraging platform-specific APIs (iOS, Android): Utilize the native APIs provided by iOS and Android for passkey creation and authentication.
• Cross-device authentication using QR codes: Implement QR code-based authentication to enable users to log in on devices that don't have passkeys stored.
• Secure storage of passkeys on mobile devices: Ensure passkeys are stored securely on mobile devices, leveraging hardware-backed security features where available.

Implementing passkeys enhances security and improves user experience, but it's crucial to consider all the angles, as Auth0 suggests, the relying party domain should not change after passkeys are enrolled, because changing the domain will invalidate all existing passkeys. As such, passkeys are created for a specific RP domain.

Now that you understand the implementation steps, let's look at integrating passkeys with mobile apps.

Security Aspects of Passkey Authentication

Are passkeys truly secure, or is it just hype? Let's dive into the security aspects of passkey authentication, separating fact from fiction.

Passkeys offer robust protection against common online threats.

• Public-key cryptography is at the heart of this security, preventing credential theft. User's private key stays securely on their device, while the public key is shared with the service. This means attackers can't use stolen credentials to access accounts, as passkeys.com explains, passkeys use public-key cryptography, This means two keys are created: one private and one public. The private key stays on your device and is never shared with anyone, making it resistant to phishing attacks. The public key is shared with the service.
• Unique passkeys are generated for each service, eliminating the risk of password reuse. If one service is compromised, other accounts remain safe.
• Local authentication reduces the risk of credential interception during transmission. Authentication happens directly on the user's device, minimizing exposure to external threats.

Passkeys inherently combine multiple factors for stronger security.

• Passkeys serve as a form of MFA by combining something you have (the device) with something you are (biometrics) or something you know (a PIN).
• Organizations can combine passkeys with other authentication factors for enhanced security. This layered approach provides robust protection against sophisticated attacks.
• Passkeys can also streamline the MFA process, eliminating extra steps. Users can verify their identity with a single action, such as a fingerprint scan or facial recognition.

While passkeys are highly secure, it's essential to consider potential vulnerabilities.

• A passkey provider compromise could expose user credentials. Choose reputable providers with robust security measures to mitigate this risk.
• Device loss or theft poses a security risk. Implement remote wipe capabilities and strong device passwords or PINs to protect passkeys stored on lost or stolen devices.
• Account recovery challenges can arise if users lose access to their devices and recovery options. Offer multiple recovery methods, such as email verification or security questions, to ensure users can regain access to their accounts.

Understanding these security aspects helps organizations confidently implement passkeys. Next, we'll explore how passkeys enhance the user experience across different devices and platforms.

Passkeys vs. Traditional Authentication Methods

Are you still relying on outdated authentication methods? Passkeys offer a more secure and user-friendly alternative to traditional approaches.

Passwords have long been the standard, but they come with inherent security risks.

• Security: Passwords are vulnerable to phishing, brute-force attacks, and credential stuffing. Users often reuse passwords across multiple sites, making them susceptible to breaches.
• Usability: Passwords require users to remember complex combinations of characters, leading to frequent password resets and frustration.
• Maintenance: Organizations spend significant resources on password resets and support, driving up operational costs.

SMS-based One-Time Passwords (OTP) add a layer of security, but they are not without their flaws.

• Security: SMS-based OTPs are susceptible to interception and SIM swapping attacks. Phishing attacks can also trick users into revealing their OTPs.
• Usability: While convenient, SMS delivery can be unreliable, especially in areas with poor network coverage. Users may experience delays or fail to receive the OTP.
• Cost: Organizations incur SMS delivery fees, which can be significant at scale. Each SMS sent adds to the overall cost of authentication.

Authenticator Apps offer stronger security than SMS-based OTPs, but they have their own set of challenges.

• Security: Authenticator apps are more resistant to phishing than passwords and SMS-based OTPs. However, they still rely on a single device, creating a single point of failure.
• Usability: Setting up authenticator apps can be complex for some users, requiring them to download and configure the app. Backing up and recovering accounts can also be challenging.
• Management: Users must manage multiple authenticator apps for different services, which can be inconvenient. Device loss or theft can lead to account lockout.

As FIDO Alliance says, passkeys are phishing resistant and secure by design.

Adopting passkeys enhances security, improves user experience, and reduces operational costs. In the next section, we'll explore how passkeys enhance the user experience across different devices and platforms.

CIAM Vendor Support for Passkeys

Passkeys are rapidly gaining traction, but how well do CIAM vendors support this new authentication method? Let's examine the passkey implementations of leading CIAM platforms.

Auth0 includes passkeys in all plans, even the free tier, which signals a strong commitment to a passwordless future. You can enable passkeys in the Database connection section of the Auth0 dashboard. Auth0 states, the relying party domain should not change after passkeys are enrolled, because changing the domain will invalidate all existing passkeys.

Auth0 allows users to sign up and log in using only passkeys, serving as a robust first and primary authentication factor.

However, Auth0 does not yet support disabling passwords entirely in the Database connection.

Microsoft Entra ID allows you to enable and enforce passkeys using Microsoft Authenticator. You can configure authentication strength policies to require passkey sign-in for sensitive resources. To enable passkeys in Authenticator, you must update the Authentication methods policy.

Enforcing attestation verifies the legitimacy of the passkey being created. If you chose to skip a second factor, you could implement custom logic when a passkey is used as an authentication method.

Many CIAM platforms are beginning to integrate passkey support, though features and implementation approaches vary. As passkeys.com notes, top tech companies like Google, Apple, and Microsoft already support passkeys. When choosing a CIAM vendor, consider their level of passkey support, including ease of implementation, supported devices, and integration with existing security protocols.

As CIAM vendors continue to enhance their passkey support, organizations can look forward to even more secure and user-friendly authentication experiences. Next, we’ll look at how passkeys enhance the user experience across different devices and platforms.
