Corbado vs Authsignal

Optimize the authentication journey, not just the passkey rollout

Corbado and Authsignal both let organizations introduce passkeys without replacing their existing identity provider, and both provide sophisticated capabilities for deploying passkeys at scale. Where they differ is in the role passkeys play within the wider authentication strategy.

Corbado is a Passkey Intelligence Platform, with a strong focus on passkey observability, adoption, rollout controls and understanding how passkey journeys perform across a customer base.

Authsignal provides production-grade passkeys through FIDO Certified infrastructure, with the flexibility to deploy and manage passkey experiences across existing customer journeys. Around those passkeys, Authsignal adds adaptive MFA, risk-based step-up, push approvals, authenticator app codes, SMS, WhatsApp and email OTP, magic links, biometrics and digital credential verification.

Corbado invests in knowing how a passkey rollout is performing. Authsignal invests in how the passkey behaves at the moment a customer signs in, and in what happens when a passkey is not the right call for that customer, device, channel or transaction.

Authsignal helps organizations orchestrate the complete authentication journey.

Corbado is a strong choice when the primary objective is to understand passkey performance and diagnose passkey failures.

Authsignal is the stronger choice when the objective is broader: to modernize authentication across the customer journey while combining passkeys with adaptive MFA, risk-based decisioning, fallback methods and omnichannel verification.

Why choose Authsignal over Corbado?

1. Build an authentication strategy around the customer.

Passkeys are an important part of modern authentication. They are phishing-resistant, fast and convenient when a customer has an enrolled credential on a compatible device.

But no single authentication method works perfectly for every situation.

Customers may use a new or unfamiliar device, lose access to their enrolled device, switch between web and mobile, contact support by phone, need to recover an account, make a high-value payment, add a new payee, access an account from a suspicious network or use a device or browser that does not support the preferred passkey flow.

A passkey-only strategy can leave organizations choosing between unnecessary friction and incomplete coverage.

Authsignal lets organizations combine passkeys with adaptive and risk-based MFA, push authentication, TOTP, SMS, WhatsApp and email OTP, magic links, biometric authentication, digital credential verification and other methods appropriate to the customer and action.

This gives teams a practical way to modernize authentication without forcing every customer and every journey into the same experience.

2. Decide whether a customer needs to be challenged at all

Corbado's passkey intelligence determines whether a viable passkey is available and routes customers toward platform authentication, cross-device authentication or an existing fallback.

Authsignal applies decisioning across the whole journey. Its rules evaluate device characteristics, IP and network data, location, transaction value, customer behavior and your own business signals, then return allow, challenge, review or block for each action.

A recognized customer on a known device completing a low-risk action continues without extra friction. A new device, a suspicious network or a high-value transaction triggers stronger authentication.

Passkey availability is one input to that decision. The decision itself is whether this customer needs another authentication step at all.

3. Protect high-risk actions after login

Signing in is only one authentication moment. For many organizations, some of the highest-risk customer actions happen after access has already been granted.

Adding a new payee, making a high-value payment, changing contact details, enrolling a new authentication method or recovering an account may each require a different level of assurance.

Corbado supports passkeys in login, second-factor and step-up scenarios. Authsignal's action-based model goes further by letting organizations create authentication policy around individual customer actions, not just the sign-in flow.

Each action can have its own risk signals, authentication requirements, permitted methods and allow, challenge, review or block outcome. A routine account view might require nothing more. A high-value payment could trigger a passkey or additional verification. An account recovery event could use an entirely different combination of methods.

This lets teams protect the moments that carry the most risk without adding the same authentication friction to every interaction.

4. Use the right authentication method for the right risk

A strong authentication strategy is not about adding more challenges. It is about applying the right level of assurance at the right time.

Corbado helps organizations improve the passkey path. Authsignal helps organizations decide when the passkey path is appropriate, when another method is better and when no additional challenge is necessary.

That distinction is important for both security and customer experience.

A passkey can reduce friction for the right customer. A fallback method can prevent account lockout. A risk-based step-up can protect a sensitive action. A no-challenge decision can avoid unnecessary authentication fatigue.

5. Extend authentication across every customer touchpoint

Corbado supports passkeys across web and native mobile applications and provides SDKs and components for those environments.

Authsignal extends authentication into additional customer touchpoints, including web, mobile, contact centers, kiosks, retail environments, in-person interactions and other assisted customer journeys.

A customer speaking with a contact center agent, for example, may need to verify their identity before an agent changes account details or performs a sensitive action. That interaction may not be suitable for a passkey alone. Authsignal can support passkeys, push, OTP, biometrics and other methods within the same authentication layer.

This matters for organizations where customers move between digital and assisted channelsWithout a shared authentication layer, teams often end up with separate policies, methods and customer experiences for each channel.

With Authsignal, organizations can create a consistent authentication strategy across the customer journey.

6. Change authentication policy without hard-coding every journey

Corbado Connect includes granular controls for passkey rollout. Organizations can phase availability by cohort, region, browser or device, use allowlists and holdbacks, and apply a kill switch during deployment.

Authsignal's no-code rules engine extends policy control across authentication actions and methods.

Teams can create conditions using Authsignal data or their own business-specific signals, then determine whether an action should be allowed, challenged, reviewed or blocked.

These decisions can live in the authentication layer rather than being repeatedly hard-coded across customer-facing applications. That makes it easier to evolve authentication as customer behavior, fraud patterns, regulations and available methods change.

Better authentication should mean less friction

More authentication is not automatically better authentication. And deploying passkeys alone does not solve every authentication use case.

Authsignal helps organizations use passkeys where they make sense while applying adaptive MFA, risk-based step-up and alternative verification methods where the customer journey requires something different.

Trusted customers can move with less interruption. Higher-risk actions can receive stronger authentication. New methods can be introduced without rebuilding the identity stack underneath them.

And because Authsignal drops on top of the identity infrastructure already in place, organizations can modernize authentication without a major migration or re-platforming project.

Frequently Asked Questions

Can Authsignal help reduce reliance on SMS OTP?

Yes. Authsignal helps organisations move customers toward phishing-resistant and lower-friction methods such as passkeys while retaining appropriate fallback options.

By reducing unnecessary challenges and shifting repeat authentication away from SMS, organisations can improve the customer experience while reducing authentication costs. Air New Zealand reduced SMS authentication costs by 90% after introducing passkeys and WhatsApp-first authentication with Authsignal

Can Authsignal support authentication beyond login?

Yes. Authsignal actions can apply authentication to payments, account changes, recovery flows and other sensitive customer actions.

Can Authsignal work with my existing identity stack?

Yes. Authsignal is designed to layer on top of existing identity infrastructure rather than requiring a migration or re-platforming project.

Does Authsignal support omnichannel authentication?

Yes. Authsignal supports authentication across web, mobile, kiosk, contact centre, retail and in-person customer interactions using the same authentication layer.

Does Corbado support adaptive MFA?

Yes. Corbado supports passkeys in MFA and step-up authentication scenarios and uses Passkey Intelligence to determine how customers should be routed through passkey, fallback and holdback journeys.

Authsignal is specifically designed around broader adaptive and risk-based authentication. Its rules engine can evaluate device, network, location, transaction and business-specific context before determining whether an action should be allowed, challenged, reviewed or blocked.

Does Corbado support digital credential verification?

Corbado publishes extensive educational content about digital credentials, including implementation guides.

However, Corbado states that it does not implement the Digital Credentials API and that its current product offering is focused on passkey authentication through Corbado Connect.

Authsignal provides Digital Credential Verification alongside its other authentication and verification capabilities.

Is Authsignal an alternative to Corbado?

Yes. Authsignal can be an alternative to Corbado for organizations looking to add passkeys on top of an existing identity stack.

However, the platforms have different areas of focus.

Corbado may be particularly suited to organizations looking for dedicated passkey observability, analytics, debugging and managed passkey rollout.

Authsignal may be better suited to organizations that want passkeys as part of a broader authentication strategy that also includes adaptive MFA, risk-based step-up, multiple authentication methods and omnichannel verification.

Is Authsignal customizable?

Yes.

Authsignal provides APIs, SDKs, pre-built UI, custom UI options, authentication methods, a no-code rules engine, session management, custom identity provider integrations, and support for external risk and business signals.

These capabilities can be combined to create authentication journeys around the requirements of the application rather than relying on one fixed authentication flow.

What are composable authentication building blocks?

Composable authentication building blocks are individual authentication and verification capabilities that engineering teams can combine into different customer journeys.

Examples include:

  • Passkeys
  • Biometrics
  • Push authentication
  • TOTP
  • OTP
  • Magic links
  • Digital credential verification
  • Risk signals
  • Step-up authentication
  • Business rules
  • Session management

Rather than requiring every customer to follow the same authentication flow, these capabilities can be combined and orchestrated differently depending on the customer, action, channel, and risk.

What is the main difference between Corbado and Authsignal?

Corbado is a Passkey Intelligence Platform focused on authentication observability, passkey adoption and managed passkey deployments.

Its two primary products are Corbado Observe, which provides visibility into authentication journeys, and Corbado Connect, which adds managed passkeys around an organization's existing IdP.

Authsignal is a drop-in authentication and orchestration layer. It combines passkeys with adaptive MFA, risk-based authentication, multiple authentication methods and omnichannel verification.

The main difference is scope. Corbado specializes in understanding and operating passkey deployments. Authsignal orchestrates when and how customers authenticate across a wider range of methods, actions and channels.

What types of organizations is Authsignal best suited to?

Authsignal is best suited to organizations that need more control over authentication across the customer journey, without replacing their existing identity stack.

Authsignal is particularly suited to organizations looking to:

  • Reduce unnecessary authentication challenges for trusted, low-risk customers
  • Deploy production passkeys and improve customer adoption
  • Introduce risk-based authentication across login, payments, recovery and other sensitive actions
  • Reduce reliance on SMS OTP by introducing lower-friction, phishing-resistant authentication methods
  • Manage authentication policy without hard-coding every rule into customer-facing applications
  • Create consistent authentication across channels, including web, mobile, contact centre and in-person journeys
  • Improve authentication conversion by balancing security requirements with customer friction
  • Modernize authentication without migrating or replacing the existing identity stack
Which is better for passkeys, Corbado or Authsignal?

Both Corbado and Authsignal support enterprise passkey deployments.

Corbado specializes heavily in passkeys. Its platform includes passkey observability, adoption analytics, user-level debugging, rollout controls and managed passkey components. Corbado reports an 80% mobile passkey activation rate in its VicRoads deployment covering more than five million users.

Authsignal provides production passkeys through FIDO Certified infrastructure and integrates passkeys into its wider authentication orchestration platform.

Air New Zealand deployed Authsignal to modernize authentication across its customer experience, using passkeys and adaptive authentication to help reduce friction while strengthening account security.

The better fit depends on the requirement. For specialist passkey intelligence and observability, Corbado is strongly focused on that problem. For organizations that want passkeys alongside adaptive MFA, risk-based authentication and other authentication methods, Authsignal provides the broader orchestration layer.
