What is Auth0?

Auth0 is rebuilding identity around actors that operate on someone else's behalf.

Auth0 is shipping delegation primitives faster than anything else in its feed. Custom Token Exchange now reaches browser sessions, agents are getting first-class identities, and Token Vault workers can pull a user's third-party tokens with nobody signed in. The dashboard work — organization search filters, a Cmd+K palette — is steady but clearly secondary to the delegation push.

What is Vault?

Vault under IBM lands 2.0.0, with FIPS 140-3 and HSM enterprise builds inside two weeks.

Vault crossed 2.0.0 in late March under its post-HashiCorp / IBM stewardship — the artifact pages now carry IBM's International Program License Agreement language alongside the existing MPL 2.0 / BSL terms. Enterprise variants followed within days: 2.0.0 enterprise FIPS 140-3 and HSM-flavored builds published April 1 and April 8, plus an sdk/v0.25.1 backport addressing a Go CVE. The recent shipping is release-engineering-heavy, not feature-heavy.

10.0

Auth0 is rebuilding identity around actors that operate on someone else's behalf.

◆ Current state

Auth0 is shipping delegation primitives faster than anything else in its feed. Custom Token Exchange now reaches browser sessions, agents are getting first-class identities, and Token Vault workers can pull a user's third-party tokens with nobody signed in. The dashboard work — organization search filters, a Cmd+K palette — is steady but clearly secondary to the delegation push.

◆ Where it's heading

The through-line is machine and proxy actors. Nearly every Early Access release this cycle answers the same question — who acted on whose behalf, and can you prove it — via act claims, per-agent credentials, and scope-pinned worker tokens. Enterprise Connect runs in a different direction: Auth0 as a modular layer over an authorization server the customer already operates, rather than a replacement for it.

◆ Prediction

The scattered Early Access pieces — Agents as Principal, Token Vault Privileged Worker, Session Delegation — are close enough in shape that the next consolidation is a single GA agent-identity product with one audit surface across all three.

2.5

Vault under IBM lands 2.0.0, with FIPS 140-3 and HSM enterprise builds inside two weeks.

◆ Current state

Vault crossed 2.0.0 in late March under its post-HashiCorp / IBM stewardship — the artifact pages now carry IBM's International Program License Agreement language alongside the existing MPL 2.0 / BSL terms. Enterprise variants followed within days: 2.0.0 enterprise FIPS 140-3 and HSM-flavored builds published April 1 and April 8, plus an sdk/v0.25.1 backport addressing a Go CVE. The recent shipping is release-engineering-heavy, not feature-heavy.

◆ Where it's heading

This is the cadence of a project completing a major-version rollout — community GA first, then RC and GA enterprise-flavor builds, then security-tracking SDK backports — rather than a roadmap pivot. The fact that FIPS 140-3 and HSM enterprise builds shipped in the same window as the 2.0 cycle is the signal worth holding onto: Vault's federal and regulated-industry posture is being kept intact under the new owner, and auth plugin version bumps suggest the wider ecosystem is staying in step.

◆ Prediction

Expect 2.x feature-bearing minor releases over the next few months, with FIPS 140-3 and HSM enterprise variants tracked alongside the community builds. GA bumps for the auth plugins to match the 2.x line are likely. Worth watching for more visible IBM branding or any Cloud-side packaging shifts that signal repositioning under the new owner.
