In 2026, identity security is extending beyond human logins: AI agents and other non-human identities need accountable access, credentials need shorter lifetimes, and incident response must measure containment—not just detection. For security teams, the practical priorities are to inventory identities, limit and trace their permissions, contain compromised sessions quickly, and make phishing-resistant authentication standard for privileged accounts.
This enterprise-focused outlook draws on 2026 material from the Cloud Security Alliance (CSA), NIST, the SANS Institute, the FIDO Alliance and the World Economic Forum (WEF). Their surveys measure different respondent populations and should not be treated as directly comparable or as universal forecasts.
1. AI agents will need identities of their own
Why this is changing
As organizations deploy agents that can use tools or take actions, treating them as invisible extensions of a human account makes it difficult to know what acted, what it was allowed to do, and who authorized it. In a 2026 CSA survey, only 18% of respondents were highly confident their current identity and access management (IAM) could manage agent identities. The survey also found that 84% doubted they could pass an audit focused on agent behavior or access controls; 21% said they maintained a real-time agent inventory, and 28% could reliably trace agent actions across all environments.
NIST authors Bill Fisher and Ryan Galluzzo argue that agents should be treated as first-class entities, with unique identifiers, credentials and entitlements tied to the identity of the user or system operating them. That principle makes accountability explicit: an agent has its own identity, but its authority is linked to the initiating user or workload.

What to implement
- Give each agent a unique identity and record its owner, purpose, environment and lifecycle in an inventory that stays current.
- Use delegated, scoped authorization tied to the user or workload that initiated the task. Grant only the tools and permissions needed for that task.
- Log tool calls, decisions and outcomes so investigators can connect an action to the agent and its authorizing identity.
- Require human approval or stronger step-up controls for high-impact actions, and revoke task-specific access when the task ends.
2. Short-lived, scoped credentials will displace static secrets
Why long-lived credentials are risky
A static API key or shared password can be copied and reused by whoever obtains it; it does not, by itself, establish the identity of the party presenting it. Long-lived bearer tokens have a similar weakness: possession is enough to present them. If one leaks, its duration and permissions determine how long and how far an attacker may be able to act.
In its 2026 survey, CSA reported that 44% of respondents were using or planning to use static API keys, while 43% were using or planning username-password combinations. NIST’s 2026 IR 8587 recommends stronger key management and token verification, automated rotation practices, and short-lived tokens for workload identity scenarios.

What to implement
- Prefer short-lived tokens restricted to the intended audience and bound to a workload or agent identity.
- Automate signing-key protection, rotation and revocation; verify tokens rather than treating possession as proof of identity.
- Keep secrets out of configuration files, markdown, logs and source repositories. Use an approved secrets-management process instead.
- Treat static keys and other long-lived credentials as documented exceptions with an owner, restricted permissions and a removal or rotation plan.
3. Identity threat response will be judged by containment speed
Detection is only the start
Identity threat detection and response (ITDR) is useful only if an alert leads to action that limits damage. SANS Institute’s 2026 findings show the gap: 68% of respondents said they detected identity attacks within 24 hours, while 55% said they contained them in that period. SANS also reported that 85% had ITDR tools, yet 55% experienced an identity-related breach in the prior 12 months. Tool adoption alone therefore does not establish effective response.
In SANS’s 2026 breakdown of identity attacks, credential phishing accounted for 35%, compromised browsers for 27%, MFA fatigue for 26%, and token hijacking for 23%. These reported categories highlight why response cannot stop at a password reset: an active session, stolen token or compromised browser may still provide access.

What to implement
- Track mean time to contain identity incidents alongside detection time, and define what counts as containment for your environment.
- Connect ITDR signals to identity providers (IdPs), privileged access management (PAM), endpoints and cloud control planes so responders can act across the relevant systems.
- Prepare and test actions to revoke tokens and sessions, disable or step up authentication for risky accounts, and investigate browser and session integrity.
- Review response exercises for the handoff from alert to action: who can revoke access, what evidence they need, and how legitimate users regain access safely.
4. Phishing-resistant access will become the privileged-user baseline
Why passkeys and security keys matter
Passwords and phishable forms of multifactor authentication can be exposed to phishing or account takeover. FIDO2 and WebAuthn use public-key cryptography; FIDO guidance explains that a passkey is bound to the online service’s domain, helping prevent a credential from being used on an impostor site. The FIDO Alliance describes hardware-backed passkeys as its highest-assurance option.
What to implement
- Require FIDO2/WebAuthn authentication for administrators and other users with high-impact access.
- Enroll a separate recovery key and test the recovery process before making the stronger method mandatory.
- Use step-up authentication for sensitive transactions and consider device posture, session, workload and behavioral signals alongside the login.
- Before choosing a hardware security key, verify compatibility with the organization’s browsers, operating systems and identity provider, plus USB or NFC needs, attestation policy and recovery process.
How to prioritize an identity-security program
The other 2026 findings indicate that identity inventories and credential hygiene deserve attention alongside agent controls. SANS reported that 75% of respondents saw growth in non-human identities, while only 8% rotated most non-human identity credentials every 90 days. It also reported that 73% used agentic AI or automations requiring credentials. Separately, WEF reported that 77% of organizations had adopted AI for cybersecurity; that figure describes AI adoption for cybersecurity, not the share of organizations that have secured AI agents.

Use those signals to assess whether your controls cover both people and machine identities, rather than assuming a human-focused IAM program covers every workload or agent. When comparing identity-security products or services, check for:
- Coverage of human and non-human identities, with real-time discovery and inventory.
- Delegated, contextual authorization; token lifetime and rotation controls; and signing-key protection.
- Traceability of agent actions and integrations with the organization’s cloud platforms and identity providers.
- Containment automation, phishing-resistant authentication, and support for relevant standards such as FIDO2, WebAuthn, OAuth 2.0 and SPIFFE.
- Recovery procedures and measurable time to contain, not merely alert volume or detection capability.
The percentages above are respondent-reported findings from separate 2026 sources, not a single representative estimate of every organization’s maturity. They do not establish a universal market-size forecast, breach cost or passkey-adoption rate.
