TL;DR: Passage will be retired on January 16, 2026, leaving teams about three months to migrate authentication flows before SDKs, APIs, and hosted services stop receiving updates and security patches, according to Authsignal. The real issue is not feature parity alone, but whether identity teams can move without turning a planned migration into an availability and risk event.
Editorial analysis by NHI Mgmt Group, based on content published by Authsignal: “Looking for a Passage alternative? Why teams are migrating to Authsignal”.
Key questions
Q: How should security teams handle an authentication platform retirement without disrupting users?
A: Start with a complete dependency map of applications, SDKs, recovery flows, and admin paths, then rank them by business criticality and migration complexity.
Q: Why does authentication migration create security risk during a platform sunset?
A: Because support ending means patches stop, but the production dependency does not.
Q: What are the signs that an auth migration is failing in practice?
A: Watch for rising login abandonment, inconsistent step-up behaviour, unexpected fallback use, and mismatches between the old and new authentication paths.
Practitioner guidance
- Map every dependency on the retiring authentication stack Identify SDKs, APIs, hosted services, and application flows that will be affected before the support end date.
- Validate replacement parity in a staging cutover Test passkey enrollment, MFA step-up, fallback paths, and user recovery flows under realistic traffic before production migration.
- Require migration telemetry and audit evidence Track drop-off, login failures, anomaly patterns, and policy decisions during rollout so you can see whether the new flow is operating as intended.
Bottom line: A retirement notice for authentication infrastructure should be treated as a governance deadline because the production dependency remains even after support ends.

Authentication retirement exposes a migration governance gap, not just a product change. When a login platform is retired on a fixed date, the core risk is not feature loss in isolation. The real problem is that identity teams must coordinate application dependencies, security validation, and user continuity under a deadline. That turns authentication into a programme-wide cutover exercise, not a simple vendor swap.
A question worth separating out:
Q: How should IAM teams compare passkeys, MFA, and orchestration during migration?
A: Treat them as separate control layers. Passkeys change how users authenticate, MFA changes when additional assurance is required, and orchestration decides which path is triggered under specific conditions. A replacement that handles one layer well but cannot preserve the others will not support a safe migration.
