Duende IdentityServer is powerful, but incomplete

You chose Duende Identity Server for good reasons: standards compliance, complete control, and flexible deployment. But when your security requirements grow beyond basic authentication, you face a choice:

Build it yourself

Months of development, ongoing maintenance

Or

Enhance your flows with Authsignal

Days to deploy, enterprise features included

Fastest way to integrate MFA and passkeys with Duende IdentityServer

Instead of replacing your investment, Authsignal seamlessly integrates to fill the gaps, giving you enterprise authentication without the enterprise development effort.

Here's how they work together seamlessly:

Duende IdentityServer handles:

Which MFA methods does Authsignal support and enhance?

In addition to passkeys, Authsignal supports a range of authentication factors, including Multi-Factor Authentication (MFA) methods such as SMS, email, TOTP, and push notifications. This ensures flexibility and security for various use cases and user preferences.

Will integrating Authsignal break my existing authentication flow?

No. Authsignal sits after your existing Duende credential validation, so your current login logic stays untouched. Users who don't need MFA continue as normal. Only users requiring additional authentication get the Authsignal flow. Zero disruption to working systems.

What if I only want this for high-risk users?

Perfect use case. Our rules engine lets you trigger enhanced auth based on risk scores, user roles, IP changes, or any custom logic. Keep simple auth for regular users, step-up security for admins or suspicious behavior.

How much will this actually cost me?
