Organizations can reduce the risk by using phishing-resistant MFA wherever practical, tightening access and recovery, removing stale identities, and limiting what any one compromised account can reach.
Why identity is a security perimeter
People, service accounts, workloads, contractors, and integrations all use identities to reach systems. Attackers therefore target more than passwords: they also seek session tokens, account-recovery routes, privileged accounts, API keys, and trusted connections between organizations. A stolen identity can be especially damaging when it works across cloud and on-premises services or carries broad administrative access.
Microsoft’s identity-management guidance reports that MFA can block more than 99.2% of account-compromise attacks. That is a Microsoft-reported research finding, not a guarantee for every organization or a claim that every MFA method is equally resistant. MFA remains one layer in a broader access-control strategy.
Where identity security commonly breaks down
Phishing, reused passwords, and account takeover
Phishing and stolen credentials remain common routes into accounts. Password reuse lets a credential exposed in one place put other accounts at risk. Attackers may also target email, VPN, remote-access, and administrator accounts because access to those systems can open paths to more resources.

MFA bypass and stolen session tokens
MFA reduces risk, but ordinary SMS codes, email one-time passwords, and push approvals can still be intercepted, proxied, or socially engineered. Adversary-in-the-middle phishing can capture authentication material; stolen session tokens can let an attacker use a session after the initial login; repeated push requests can pressure a user into approving one. MFA is only as strong as its enrollment, recovery, and session-protection paths.
Unmanaged, legacy, and machine identities
Organizations can lose track of service accounts, workload identities, old user accounts, API keys, and credentials embedded in automation. Dormant identities and legacy authentication paths may remain usable after they are no longer needed. If onboarding, role changes, and offboarding are not timely and auditable, access can outlast the person or process that justified it.
Excessive privilege and lateral movement
Accounts with broad, persistent permissions give an attacker more room to move after a compromise. Using an administrator account for routine work increases exposure, while standing privileges can make a single stolen identity a route to many systems. Poor separation between systems can magnify the impact.

Fragmented access across hybrid and third-party systems
Cloud services, on-premises systems, remote workers, contractors, and integrations may each have different access policies. Federation links, OAuth grants, API keys, and third-party trust can create paths that are easy to overlook. A policy applied to one service or tenant does not necessarily protect the others.

For administrators and other high-risk users, prioritize FIDO2 security keys or passkeys where the service and users’ devices support them. These phishing-resistant methods bind authentication to the legitimate site or device, reducing reliance on replayable secrets. Check account support, device compatibility, cross-device needs, accessibility, and how backup authentication will work before rollout; secure backup and recovery matter as much as enrollment.
Where phishing-resistant MFA is not yet available, require MFA rather than leaving the account password-only. CISA identifies number matching as an interim improvement over unrestricted push approval while organizations move toward phishing-resistant MFA. It is a transitional measure, not an equivalent substitute.

Microsoft’s 2025 reporting says 92% of employee productivity accounts are protected by phishing-resistant authentication methods. That figure describes the accounts covered in Microsoft’s reporting; it should not be read as a universal adoption rate or a promised outcome for other organizations.
Build controls around the whole identity lifecycle
1. Inventory identities and access paths
List human, service, workload, and external identities alongside the applications, privileged roles, tokens, federation links, and third-party relationships they can reach. Identify which accounts are active, who owns them, what they can access, and how they authenticate. This inventory gives teams a basis for prioritizing protections and finding dormant accounts or stale credentials.
Recommended Free Tools
2. Enforce MFA and remove weak entry points
- Require MFA for every service that supports it, beginning with administrators, email, VPN, remote access, and sensitive applications.
- Prioritize phishing-resistant methods for administrators and high-risk users; use number matching as an interim step where migration takes time.
- Disable legacy authentication paths that bypass modern controls, and reduce exposed entry points.
3. Apply conditional access and protect sessions
Use conditional-access policies to evaluate identity, device, location, and risk signals, and apply them consistently across relevant services and tenants. Use token-protection capabilities where supported. Treat a successful login as one signal, not proof that every later request is safe.

4. Limit privilege and contain compromise
- Keep separate administrator and everyday accounts.
- Grant only the permissions needed for each role, and use just-in-time or time-limited elevation where available.
- Verify identity, device, and context for privileged sessions; log administrative activity.
- Design access boundaries on the assumption that an account may be compromised, so one identity cannot automatically reach every system.
5. Secure enrollment, recovery, and offboarding
Review enrollment and recovery flows as carefully as normal sign-in because attackers may target the weakest step. Use strong identity proofing for enrollment and recovery, and temporary access passes where appropriate. Make onboarding and offboarding time-bound and auditable; remove access and stale credentials when they are no longer justified.
6. Reduce machine-identity risk
Inventory service and workload identities, their owners, credentials, and permissions. Where appropriate, migrate user-based automation to workload identities or certificates. Remove unused identities and stale secrets, and review API keys and OAuth grants alongside human access rather than treating them as a separate concern.
7. Review third-party trust
Apply consistent access requirements to contractors, integrations, and external organizations. Review federation, OAuth grants, API keys, and other third-party trust relationships regularly. Sensitive applications should use enterprise-managed identities where practical, with access limited to the purpose and period required.

Measure whether the controls are working
Track measures that reveal coverage and operational friction, rather than relying on a single MFA-on/off figure:
- Share of users and privileged accounts enrolled in phishing-resistant authentication.
- Coverage of conditional-access enforcement across important applications and tenants.
- Privileged-account protection, including use of separate admin accounts and time-bound elevation.
- Time to complete recovery and offboarding, alongside review of whether those flows remain secure.
- MFA-fatigue and lockout support tickets, which can expose usability problems or attack pressure.
- Identity inventory coverage, including workload identities, tokens, and third-party connections.
Microsoft’s Secure Future Initiative described phishing-resistant MFA as essential for reducing credential-based attack risk. The practical implication is to make it the target for accounts and services that support it, while closing gaps elsewhere with layered controls rather than treating any single authentication setting as a complete solution.
