Authentication continues to evolve as organizations push for more secure and user-friendly methods. Passwordless authentication eliminates passwords altogether, relying instead on methods like biometrics, magic links, and one-time codes. It simplifies both the user experience and the management of authentication systems. But for robust implementations, many engineering teams lean on sub-processors to enhance the capability and compliance of their solution.
This blog will cover exactly what passwordless authentication sub-processors are, their role in modern architectures, and what to consider when integrating them into your stack.
Understanding Passwordless Authentication Sub-Processors
Sub-processors provide specialized services or components that integrate into your passwordless authentication workflows. While your main authentication provider might handle core tasks like identifying and verifying users, sub-processors often address complementary needs.
Examples include:
- Sending SMS for one-time codes.
- Generating and delivering login links via email.
- Verifying device identities or geolocations.
- Managing biometric data for identity confirmation.
These sub-processors operate behind the scenes, allowing the main authentication provider, and by extension your application, to deliver seamless user experiences without building everything from scratch.
Why Use Sub-Processors for Passwordless Authentication?
Passwordless authentication systems can be complex. Handling all associated processes internally might stretch resources and introduce risks. Bringing sub-processors into the equation expands your capabilities without extensive in-house development.
Here’s a breakdown of what sub-processors add to the table:
1. Scalability
Sub-processors handle tasks like message delivery or user verification at scale. For example, globally distributed services ensure OTPs or magic links reach users anywhere without delay.
2. Regulatory Compliance
Many sub-processors specialize in compliance with regulations like GDPR, HIPAA, or CCPA. When you rely on their expertise, certification processes for your passwordless workflows become less burdensome.
3. Improved Reliability
Delegating specific responsibilities, such as biometric verification or token signing, to dedicated sub-processors improves the reliability of your system. These services are built to focus solely on that function, minimizing failure points in your architecture.
4. Time-to-Market
Building passwordless features in-house takes time, especially if you want to ensure security and reliability. By leveraging pre-built and battle-tested sub-processors, you save engineering hours and can deploy faster.
Risks to Consider When Selecting Sub-Processors
While sub-processors can elevate your authentication pipeline, thoughtful selection is critical to avoid introducing vulnerabilities or inefficiencies. Below are key considerations:
1. Data Security
Your sub-processor handles sensitive user data like email addresses, phone numbers, or even fingerprints. Verify they implement robust encryption protocols and conduct regular security audits.
2. Third-Party Dependencies
Every integration introduces an external dependency. If their service experiences downtime, it could disrupt your workflows. Make sure to evaluate SLAs (Service Level Agreements) and their uptime guarantees.
3. Economic Costs
Adding too many sub-processors can inflate costs quickly. Overlapping functionalities between services should be minimized, and you should regularly evaluate ROI.
4. Data Sharing Across Borders
Ensure sub-processors follow data sovereignty rules, especially if deploying in highly regulated industries or countries. For instance, does your sub-processor store and move data per GDPR mandates if you're operating in Europe?
Common Sub-Processors Used for Passwordless Authentication
Below are examples of frequently adopted sub-processors, categorized by their roles:
- Communications: Twilio, SendGrid, Postmark
- Biometrics: iProov, SmilePass
- Identity Verification: Auth0 Signals, Jumio
- Token Management: Firebase Authentication, AWS Cognito
These providers integrate with widely used platforms, extending baseline authentication capabilities to meet advanced scenarios.
