What you'll learn: a practical, 30-day plan to run a SaaS access review that reduces real risk—fewer stale accounts, fewer runaway integrations, and a safer path to scale. This June 2026 update adds actionable guidance for token inventories, adaptive and continuous session controls, machine identity governance, and the current state of passkeys/passwordless adoption in enterprise IdPs and SaaS vendors.

Who this is for: IT administrators, security leads, RevOps, “accidental admins” at startups, and anyone who owns or influences SaaS governance. If you manage 6–200 apps and want to stop treating identity as an annual checkbox, this is for you.

Why this matters now: Identity is still the primary attack surface for SaaS-first orgs. In 2026 we've seen two converging realities: (1) passwordless (passkeys/FIDO2) and continuous access evaluation (CAE) are widely supported in major IdPs and browsers, and (2) attackers are increasingly chaining ephemeral tokens, OAuth grants, and machine credentials to bypass traditional controls. A focused 30-day review is the fastest, highest-leverage way to cut risk in a landscape where human and machine identities both need governance.

Prerequisites / Context (what you should have before Day 1)

You don't need a large security team. You need authority, a few tools, and owners.

  • Identity provider (IdP): Microsoft Entra ID, Okta, Google Workspace, JumpCloud, or similar. By 2026 most major IdPs include features beyond SSO: token/OAuth grant inventories, session management, and APIs for revocation. Know what your IdP can enumerate and revoke programmatically.
  • Source of truth: HRIS (Workday, Rippling, BambooHR) for employees; a vendor/contractor list for contingent workers. Your deprovisioning automation must tie to these sources.
  • App owners and admins: one named owner per app who can approve changes and at least one admin who can run exports and apply changes. Include an owner for machine identities (e.g., platform eng lead).
  • Decision-maker: someone who can approve enforcement (require SSO, revoke local logins, enforce expiration rules).
  • Optional but highly useful: an Identity Governance & Administration (IGA) tool, a CASB (Cloud Access Security Broker), or a token/integration inventory feature in your IdP. Machine identity platforms (HashiCorp Boundary/ Vault, CyberArk, cloud-native workload identity) help govern API keys and service principals.

Terms (quick refresher):

  • SSO (Single Sign-On): IdP authenticates users; apps trust the IdP.
  • SCIM (System for Cross-domain Identity Management): automates account create/update/disable from the IdP.
  • RBAC (Role-Based Access Control): grants based on roles/groups rather than per-user exceptions.
  • Passkeys / FIDO2: device-bound public-key credentials that enable passwordless logins; by 2026 they are a standard option in mainstream desktop and mobile browsers and in many enterprise IdPs.
  • CAE (Continuous Access Evaluation): a mechanism that shortens the window between a policy change (like a revocation) and when that change is enforced for active sessions—useful for immediate reaction to incidents.

Overview: 30-day plan (what success looks like)

  1. Days 1–3: Build a usable app and token inventory (start with 8–12 apps).
  2. Days 4–7: Define scope and “high risk” access—explicitly include machine identities and OAuth clients.
  3. Days 8–12: Export and reconcile users, tokens, OAuth grants, and session artifacts.
  4. Days 13–17: Enforce SSO + passkeys/MFA for privileged users; disable local-password auth for Tier 1 apps.
  5. Days 18–22: Turn on SCIM and automated deprovisioning; enable CAE or session revocation where supported.
  6. Days 23–26: Implement RBAC and machine-role least privilege; swap static keys for short-lived credentials or workload identity federation.
  7. Days 27–30: Run review meetings, apply changes, collect evidence, and set recurrence plus KPIs to monitor progress.

Step 1 (Days 1–3): Build an app and token inventory you can actually use

If you only do one thing, make this your priority. The inventory is your map.

  1. Export IdP-integrated apps, assignments, and token artifacts. From the IdP console and vendor portals, export enterprise apps, assigned groups, service principals, OAuth clients, and any available token lists (API keys, refresh tokens, OAuth consent grants).
  2. Pull procurement and cloud spend data (last 180 days). Map vendor names to app names; finance systems surface shadow SaaS and self-serve purchases that teams have created outside central procurement.
  3. Inventory machine identities and integrations. Include CI/CD service accounts, cloud service principals (AWS/GCP/Azure), OAuth clients registered by teams, bot users, and any secrets in secrets managers. Look for patterns: CI pipelines often surface the same key across projects.
  4. Create a single inventory sheet or canonical table with columns: App, Owner, Admins, SSO? (Y/N), SCIM? (Y/N), Token inventory? (Y/N), CAE/session revocation? (Y/N), Passkeys available? (Y/N), User count, Machine identities count, Data sensitivity, Criticality, Notes, Last review date.

Why this matters: Vendors and teams spin up integrations faster than security can track them. An inventory ties finance, IdP, and engineering lists into one source of truth and forces ownership: each row must name an owner who will sign off on changes.

Step 2 (Days 4–7): Choose scope and define high-risk access (machines included)

Not all access is equally dangerous. Machine identities and OAuth clients now represent a big share of attack paths.

  1. Pick 8–12 apps and label Tier 1 (sensitive) or Tier 2. Prioritize customer data stores, code repos, billing portals, IAM consoles, CI/CD, and data pipelines feeding AI models.
  2. Define high-risk roles and actions for each app: super admin, billing manager, org owner, "manage integrations," "create API keys," "grant OAuth consent," "create OAuth apps," and "export data."
  3. Include machine identity risks: long-lived API keys, service principal secrets, CI/CD tokens, and OAuth refresh tokens. Define permissible age for credentials (e.g., tokens >30–90 days should be flagged) and who can rotate/revoke them.
  4. Set rules of the road: require SSO + passkeys/MFA for admins, no local passwords for Tier 1, enforce short-lived access for contractors, and require explicit, time-bound exception approvals.

Concrete example: In GitHub Enterprise, "Owner" and "Billing" remain high risk; in Slack and Teams, audit apps with "manage tokens" or "post as user" scopes; for CRMs, limit "Export" and "API user" roles. Add "who can register OAuth clients" to the high-risk list—those registrations can mint tokens that bypass admin-reviewed flows.

Step 3 (Days 8–12): Export and reconcile users, tokens, OAuth grants, and sessions

Accounts are not the whole story anymore—tokens and sessions are first-class citizens.

  1. For each app, export: users, roles, last login, auth method (SSO/password/passkey), service accounts, API keys, OAuth clients/grants, active sessions, and device session details if available.
  2. Reconcile against HRIS and contractor lists. Flag orphaned employees, expired contractors, and unapproved service accounts. Record last activity and session origin (IP, device) where possible.
  3. Inventory tokens and OAuth grants. Flag long-lived API keys and refresh tokens older than your policy. Note which apps and IdPs support programmatic revocation or CAE to invalidate active sessions immediately.
  4. Flag anomalies: duplicate identities, local-password accounts, never-accepted invites, obsolete integrations, and service accounts with broad permissions.

Why this matters: Attackers increasingly chain OAuth and API tokens to move laterally. Removing stale tokens and orphaned service accounts is often the fastest way to reduce blast radius.

Step 4 (Days 13–17): Enforce SSO + passkeys/MFA and kill password bypass

Passkeys and hardware-backed FIDO2 are mature in 2026 and should be standard for privileged access. Passwords remain the weakest link.

  1. Require SSO for Tier 1 apps. Where the vendor supports enforcement, block local password auth. Use your IdP's enforcement APIs to detect bypass.
  2. Enforce strong MFA or passkeys at the IdP. Favor passkeys (passwordless) or hardware security keys for admins. Use authenticator apps as fallback; avoid SMS-only MFA.
  3. Disable local authentication for users. Restrict local credentials to documented break-glass accounts only and monitor those accounts closely.
  4. Design break-glass: two vaulted accounts per critical app, protected with hardware MFA, tested quarterly, and not tied to a single employee.

Tradeoffs: Enforcing SSO and passkeys can break legacy connectors and automation; provide an explicit, short-lived exception process and compensating controls (session monitoring, token rotation, elevated logging).

Step 5 (Days 18–22): Turn on SCIM, CAE, and automated deprovisioning

SCIM remains the best automation for reducing human-account drift. In 2026 add CAE and session revocation to your checklist where available.

  1. Enable SCIM for Tier 1 apps and any app with admin/export privileges.
  2. Map IdP groups to app roles including attributes like department and employment type to support role mapping.
  3. Pilot lifecycle tests: create user → role assigned; change department → role updated; terminate → account disabled and sessions revoked. Confirm CAE/real-time session termination if vendor supports it.
  4. Define deprovision timing for terminated employees; for contractors, align deprovision with contract end dates or use short-lived access tokens.

Limitations & workarounds: Some vendors still have partial SCIM or limited session APIs. Where automation is incomplete, document manual steps, or replace critical vendors whose gaps pose unacceptable risk.

Step 6 (Days 23–26): Implement RBAC that matches how teams actually work (include machine roles)

Make roles small, meaningful, and enforceable. Treat machine identities the same as people: owner, limited scope, rotation schedule.

  1. List core job functions and machine roles per app (Support Agent, Sales Rep, Billing Analyst, CI Runner, Deployment Bot).
  2. Create least-privilege roles and map IdP groups to them. Avoid catch-all Admin roles; split capabilities (read, write, manage-integration, billing).
  3. Convert individual grants into group-based grants and require time-bound exceptions for unique cases.
  4. Replace static keys with short-lived credentials or workload identity federation (OIDC) where possible; if static keys persist, require storage in a secrets manager, strict rotation, and audit trails.

Example: Swap a shared "deploy" API key used in CI for an OIDC-based workload identity that exchanges a certificate for a short-lived token issued by the cloud provider. If that's not possible, store the key in a secrets manager and rotate it automatically via pipeline hooks.

Step 7 (Days 27–30): Run the review, act, and lock in recurrence

Convert evidence into decisions and automate the process going forward.

  1. Prepare a review packet for each app with users, privileged users, non-SSO logins, orphaned accounts, service accounts, token lists, active session evidence, and proposed changes.
  2. Hold 30–45 minute review meetings with the app owner and admin. Approve removals, role changes, and token revocations live. Use IdP/vendor APIs during the meeting where possible to show live remediation.
  3. Execute changes within 48 hours and re-export to confirm—store exports and change logs as evidence.
  4. Set cadence and KPIs: Tier 1 quarterly, Tier 2 semiannual. Track percent of apps with enforced SSO, percent of privileged users on passkeys, time-to-deprovision (goal: 24 hours for terminated employees), and percent of machine identities using short-lived credentials.
  5. Store evidence centrally: exports, approvals, and remediation records in your IGA tool, compliance folder, or ticketing system for audits.

Common mistakes (and how to avoid them)

  • Boiling the ocean: start with 8–12 apps and the highest-risk roles; you can scale the process after you prove the playbook.
  • Ignoring tokens and OAuth grants: accounts may be gone but tokens persist—inventory and revoke where necessary.
  • Allowing permanent exceptions: every exception needs an owner and an expiry; automate reminders.
  • Not involving app owners: they understand business workflows; security provides guardrails, owners approve changes.
  • Assuming "passwordless" fixes everything: passkeys reduce credential theft risk but don't replace governance of OAuth apps or machine identities.

Pro tips (to get better results with less friction)

  • Tighten admin roles first: highest risk reduction per hour—start there.
  • Name IdP groups for scale: use a predictable pattern: APP-Tier-Role (e.g., SFDC-Tier1-SalesOps).
  • Measure time-to-deprovision: from HR termination to access removal; target under 24 hours for employees.
  • Limit token lifetimes: prefer short-lived tokens, ephemeral certs, and workload identity. Rotate any long-lived key immediately.
  • Document a golden path per app: one short SOP for requesting access, approvals, and removal.
  • Use conditional access and CAE: enforce device posture and session restrictions for privileged sessions; enable CAE where your IdP and apps support it.
  • Monitor token usage in your SIEM: flag unusual token grants, multiple IPs, or token exchanges from unexpected systems—tokens rarely used should be removed.

FAQ

Do I still need SCIM if I have SSO and an IGA tool?

Yes. SSO handles authentication; SCIM automates lifecycle actions (create, update, disable). IGA tools help with attestation and workflows, but SCIM reduces manual work and prevents gaps between HR events and app state. Treat SCIM as the automation layer that keeps your IdP and apps synchronized.

How should I treat OAuth grants and third-party AI integrations?

Treat every OAuth client and AI integration as an access vector. Inventory active grants, link them to owners, require explicit business justification, and revoke any grant without a current business need. For AI tools, prefer corporate SSO and least-privilege connector permissions; avoid granting export-level access unless necessary. Log every grant and monitor data exfil patterns.

What about machine identities and CI/CD tokens?

Treat machine identities like people: assign an owner, limit permissions, prefer workload identity federation (short-lived tokens issued at runtime), store secrets in a secrets manager, and rotate regularly. Include machine-role attestation in your privileged access cadence—monthly or whenever CI/CD pipelines change.

How many break-glass accounts should we keep?

Two per critical system is common practice. Store them in a vault with hardware MFA, test quarterly, and ensure they aren’t tied to a single person. Access should be logged and require dual approval where possible.

What's the fastest win if we only have a week?

Lock down privileged access in your top 3 apps: enforce SSO + passkeys/MFA for admins, remove orphaned admin accounts, and revoke long-lived tokens or API keys you can’t justify. That alone reduces the primary attack surface for many SaaS incidents.

Wrap-up: Identity is the key ring for your SaaS house. In 2026, the tools are better—passkeys, CAE, token inventory, and workload identity federation—but attackers have adapted. A focused 30-day review that inventories tokens, brings machine identities under governance, enforces SSO/passkeys for privileged users, and automates deprovisioning will cut real risk quickly. Repeat the cycle and measure the right KPIs; over time it becomes the backbone of secure SaaS operations.
