Seamless Transition—Without Breaking Your Existing IAM

Keymate enables safe, staged migration from your legacy IAM system by operating in parallel mode. No "Big Bang"—you can move apps one by one while both systems remain in sync and operational.

Seamless Transition—Without Breaking Your Existing IAM

Modernize Without Breaking What's Already Working

Most enterprises run critical systems on legacy IAM platforms. A risky cutover is not acceptable. Keymate solves this with native parallel IAM compatibility: Accept login from either legacy IAM or Keymate. Exchange legacy tokens for Keymate tokens securely. Support session federation without SSO rewrite. Continue using legacy IAM during transition. Migrate users on-demand—only when they log in. Maintain consistent token structure and session logic. Centralize policy enforcement while IAMs run in parallel. This unlocks smooth, app-by-app IAM modernization—without disruption, without rewriting logins, and without downtime.

Parallel IAM Operation

Enable safe, staged migration from legacy IAM systems through parallel operation and gradual token exchange.

Example: Run legacy and modern IAM systems side-by-side

Key Components:

Legacy IAM Compatibility
Token Exchange Layer
Session Federation
On-Demand Migration
App-by-App Transition

What Makes It Unique

Token Exchange Support

Legacy tokens can be verified and exchanged for Keymate JWTs

Login Compatibility Layer

Users can log in via Keymate using legacy IAM credentials

No Change Required in Legacy Apps

Existing applications continue to authenticate as before

On-Demand User Migration

Users are created in Keymate the moment they first log in

Credential Sync Optional

Passwords may remain in the legacy IAM; no double storage

Session Alignment

Session info (org, role, identity) preserved across systems

App-by-App Transition Support

Migrate one application at a time—no global cutover needed

Audit & Tracing

Track which logins originated from which IAM and how tokens were mapped

Frequently Asked Questions

No. Keymate supports lazy user creation—users are added when they log in.
Yes. You can choose which applications authenticate via Keymate and which stay on legacy IAM. Both systems operate in parallel until you complete the migration.
Keymate uses a proxy or integration layer to call the legacy IAM and validate tokens.
Yes. Once the token is exchanged, the session continues under Keymate context with all features (FGAC, policies, logs, etc.)
No. You can keep the legacy IAM in place for those apps, and use Keymate where modernization is needed.
