SuperTokens is hardening SAML and building a migration path off other auth providers.
SuperTokens is an open-source authentication service, and its core repo is running a 12.0 canary line alongside stable patches. The work in this window falls into two piles: SAML security — XML signature wrapping protection in 12.0.2-canary, further hardening in the 12.0.10 release — and migration mode, where new core-user-data records can be created as MIGRATED and the transition is now blocked while inconsistent users exist. Release notes are thin, usually a PR title or two per tag.
WorkOS is building identity for agents while quietly fixing the sign-up funnel.
WorkOS ships several small entries a week, and August splits cleanly in two. One half is authentication housekeeping for human users: an Android SDK, deliverability checks that reject undeliverable addresses at sign-up, invitation acceptance counting as email verification, and a reversible SCIM proxy for migrating directory connections without downtime. The other half is agent infrastructure — Agent Registration via the auth.md protocol, and the Pipes Token Proxy that calls third-party APIs on a user's behalf without the application ever touching their token.

Migration mode plus account-linking exploration is the tell: this is infrastructure for importing an existing user base from another provider without breaking identity linkage mid-flight, and the guard added in 12.0.5-canary shows they hit the inconsistent-state case in practice. The SAML work runs in parallel because enterprise SAML is what a team is usually migrating toward. Also worth noting: an automated contributor, supertokens-agent-runner, opened its first PRs in this window, so part of the fix and test volume is now agent-authored.
A stable 12.x release consolidating the canary migration-mode work is the readable next step, likely once the MIGRATED transition guards have run without incident. More SAML hardening should be expected given two separate fixes landed in this window alone.

The agent work is the strategic line. Registration gives an agent an identity of its own instead of a borrowed human session; the token proxy means an application acting for a user never holds the credential. Together they describe a stack where an agent can be authorized, audited and revoked as a first-class principal. The human-auth releases are conversion and migration work — the deliverability check and SCIM Bridge both remove reasons a customer stalls — which is what a developer-infrastructure company does while its next category is still forming.
Registration and the token proxy leave scoping and revocation as the visible gaps, so expect per-agent permissions or consent surfaces next. Whether auth.md gains adoption beyond WorkOS is not something these entries can answer.
