Existing Apps / Drop-In Authentication
Add passkeys and adaptive MFA to any existing application without replacing the identity provider or migrating user data.
The challenge
Many organisations want stronger authentication but cannot justify the risk and cost of migrating their existing identity provider or user database. A drop-in layer that adds passkeys and step-up MFA to the current authentication flow lets teams modernise security without the disruption of a full re-platform.
Key capabilities in this use case
Sit-alongside integration
Add Authsignal as a layer in front of or alongside an existing IdP such as Cognito, Keycloak, Azure AD B2C or Auth0.
No user-data migration
Enrol and verify users without moving their existing credentials or profile data into a new system.
Custom authentication support
Integrate with bespoke, home-grown login systems that do not use a standard identity provider.
Rapid deployment
Use SDKs and pre-built components to add passkeys and MFA in a matter of days rather than months.
Core capabilities
IdP-agnostic integration
Works alongside common and custom identity providers.
SDKs and pre-built UI
Accelerates front-end and back-end integration.
No migration requirement
Existing user stores remain untouched.
Incremental rollout support
Enable for a subset of users or flows first.
Modernising authentication without a re-platform
A logistics company runs a custom-built authentication system that predates modern identity standards and has no near-term plan to replace it. Rather than rebuilding the login system, the team integrates Authsignal as a drop-in layer that adds passkey enrolment and adaptive MFA to the existing flow, calling Authsignal's API at the login and step-up points. Within weeks, customers are offered passkeys during login while the underlying user database and session management remain unchanged. The security team gains modern authentication capabilities without the multi-year cost and risk of an identity-provider migration.
- 1Authsignal called at existing login checkpoints
- 2Passkey and MFA enrolment layered onto current flow
- 3Rollout expanded once initial cohort is validated
Expected outcomes
- Modern authentication without a re-platform
- Faster time to deployment than a full migration
- Preserved investment in existing identity infrastructure
- Incremental, lower-risk adoption path
How CyberLane helps
CyberLane assesses the existing authentication architecture and advises on the least disruptive way to layer Authsignal in, including which flows to prioritise for an initial drop-in deployment.
- Current authentication architecture review
- Drop-in integration plan
- Priority-flow selection for initial rollout
- Vendor evaluation support
CyberLane is independent and works on the decision rather than the deployment. Product-specific delivery is coordinated with the vendor or a qualified implementation partner.
