HealthInsight Authenticators

Monitor and manage authentication health across your Okta org

HealthInsight is Okta’s built-in security dashboard that gives administrators real-time visibility into the health of their authentication ecosystem — identifying risky configurations before they become vulnerabilities.

Security dashboard monitoring

Real-time authentication health monitoring with Okta HealthInsight

🏅 Health Score

Overall authenticator health score, flagging weak or deprecated methods like SMS OTP.

⚡ Risk Signals

Detects authenticators with low adoption or policy mismatches and sends alerts to admins.

🔑 Authenticator Types

Covers Okta Verify, FIDO2/WebAuthn, Email Magic Link, SMS, Voice, and hardware tokens.

🛠 Recommendations

Suggests remediation steps such as enforcing phishing-resistant authenticators org-wide.

02

Authentication Policies

Define who can access what, when, and with which authenticator

Authentication Policies allow granular, rule-based control over app access. Each policy is composed of conditions, rules, and authenticator requirements.

Conditions

  • User group membership
  • Network location (IP)
  • Device platform
  • User risk level
  • Time of access

Rules

  • Allow access
  • Deny access
  • Prompt for MFA
  • Require re-auth
  • Challenge step-up

Authenticators

  • Okta Verify (Push/TOTP)
  • FIDO2 / WebAuthn
  • Email Magic Link
  • SMS / Voice OTP
  • Hardware Token (TOTP)
MFA Multi-factor authentication security

Multi-factor authentication enforces layered security at every access point

03

Global Session Policy

Controls user session lifetime and re-authentication requirements across the org

Unlike app-level Authentication Policies, the Global Session Policy applies to all apps in your org. Rules are evaluated top-down; the first matching rule wins.

🕐 Max Session Lifetime

Set an upper limit (e.g. 8 hours) for how long any session remains valid.

💤 Idle Timeout

Auto sign-out users after a period of inactivity to reduce exposure risk.

🔄 Re-auth Frequency

Force re-authentication at defined intervals for sensitive workflows.

🍪 Persistent Cookies

Control “Remember Me” behavior and persistent session cookies per group.

🌐 Network Restrictions

Restrict or enforce sessions based on trusted vs. untrusted network zones.

👥 Per-Group Overrides

Different policies for different user groups — e.g. contractors vs. employees.

Best Practice: Combine a short idle timeout (2 hours) with re-authentication enforcement for sensitive applications to significantly reduce risk from unattended sessions.
04

Identity Threat Protection (ITP)

AI-powered continuous authentication and risk-based threat response

Okta’s Identity Threat Protection delivers continuous risk evaluation beyond the initial login moment — integrating with leading security tools via the Shared Signals Framework (SSF).

🔗 Threat Signals

Integrates with CrowdStrike, Zscaler, and other security tools via Shared Signals Framework.

🤖 Risk Engine

Evaluates user behavior in real-time: impossible travel, new devices, credential stuffing patterns.

⚡ Automated Actions

Force re-auth, revoke sessions, lock accounts, or alert admins based on risk score.

🚪 Universal Logout

Terminate all active sessions across all apps simultaneously when a threat is confirmed.

05

User Profile Policies

Control how user profile attributes are sourced, updated, and protected

Okta can act as the profile master or defer to AD, LDAP, or HR systems (Workday, BambooHR). Attributes can be individually locked to prevent account takeover via profile edits.

AttributePermission
First / Last NameRead-only (sourced from AD)
Email AddressUser editable
Phone NumberUser editable (MFA use)
Department / TitleRead-only (HR system)
Profile PhotoUser editable
Custom AttributesAdmin configurable
06

Identity Providers & Delegated Authentication

Connect external identity sources and delegate authentication to trusted providers

Okta supports federation with a wide range of external IdPs via SAML 2.0, OIDC, and native integrations, enabling organizations to achieve SSO and MFA without migrating credentials.

SAML 2.0

  • Azure AD
  • ADFS
  • PingFederate
  • Any SAML-compliant IdP

OIDC / Social

  • Google
  • Facebook
  • Apple
  • LinkedIn / GitHub

On-Prem / Directory

  • Microsoft Azure AD
  • Active Directory
  • LDAP
  • Okta AD Agent sync
Delegated Authentication: Okta validates credentials against an external directory (AD/LDAP) without storing the password — ideal for organizations not yet ready to migrate passwords into Okta but wanting SSO and MFA benefits immediately.
1
User enters credentials in Okta

Standard login screen — no change to user experience.

2
Okta sends validation request to AD

Credentials forwarded securely to Active Directory.

3
AD responds pass/fail

The password is never stored in Okta at any point.

4
Okta issues session token

On success, Okta creates a session and applies its MFA/SSO policies.

07

Networks & Behavior Detection

Define trusted network zones and detect anomalous access patterns

Network security monitoring zero trust

Zero trust network architecture — trust nothing, verify everything

🌐 IP Zones

Define IP ranges/CIDRs as trusted or blocked. Corporate office IPs can be marked as a trusted zone.

🛡 Dynamic Zones

Use threat intelligence feeds to auto-block known malicious IP ranges in real time.

🚫 Blocklist Zones

Explicitly block specific IPs, ASNs, or Tor exit nodes from accessing Okta entirely.

📍 New City

Login detected from a city the user has never accessed from before — triggers risk signal.

💻 New Device

Access from a device fingerprint not previously seen for this user account.

✈️ Velocity Check

Impossible travel — logins from geographically distant IPs within impossibly short windows.

08

Advanced Posture Checks & Device Assurance

Evaluate device security state before granting access to critical resources

Advanced Posture Checks evaluate device security at login time and continuously. Combined with Device Assurance Policies, they ensure only healthy, compliant devices access your apps.

Endpoint device management security compliance

Device assurance policies enforce compliance across Windows, macOS, iOS, and Android

Okta API Security

Managing API tokens, OAuth 2.0 scoped access, and API Access Management

🔑 API Tokens (Legacy)

SSWS tokens tied to an admin user. Not recommended — they don’t expire and inherit creator permissions.

✅ OAuth 2.0 / OIDC

Preferred method. Short-lived access tokens with specific scopes. Service apps use client credentials flow.

🛡 API Access Management

Okta as OAuth 2.0 Authorization Server for your custom APIs. Define custom scopes and policies.

📦 Official SDKs

Node.js, Python, Java, .NET, Go — all handle token management, retries, and pagination.

API Security Best Practices

1

Never use API tokens for automated processes. Use OAuth 2.0 service apps with the narrowest possible scopes.

2

Rotate API tokens regularly. A leaked token inherits full admin permissions.

3

Use Okta’s System Log API to monitor all API activity. Alert on bulk user operations or policy changes via API.

4

Restrict API token creation to Super Admins only. Audit who has created tokens in Security → API.

5

Implement IP allowlisting for API Access Management authorization servers to block unauthorized clients.

Security is a Journey, Not a Destination

Okta’s layered architecture gives you the building blocks to achieve Zero Trust identity security. Every layer reinforces the next.
