TL;DR: Centralized identity platforms create a concentrated attack surface because phishing, token theft, OAuth consent abuse, and app registration persistence can move from access to data exfiltration in hours, according to SecureAuth’s technical analysis. The core issue is not login security alone but the assumption that a token remains trustworthy after issuance, which no longer holds under modern identity-first attacks.

By the numbers:
- 80% of breaches use valid credentials, showing why token and session abuse now matters as much as password compromise.
- 277 days is the average breach detection time cited in the paper’s risk analysis, which leaves attackers a long window inside trusted identity paths.
- 1,000+ enterprises can be affected by a single Mega IdP breach, according to the paper’s blast-radius analysis.
Questions worth separating out
Q: What breaks when identity platforms trust tokens after login?
A: Static trust breaks because the attacker can keep using a valid session after the original authentication event.
Q: When should organisations prioritise continuous authorization over longer token lifetimes?
A: Organisations should prioritise continuous authorization when the protected action is more sensitive than the login event that created the token.
Q: What are the signs that OAuth consent governance is failing?
A: Common signs include broad scopes granted to unfamiliar applications, app registrations that survive beyond their business purpose, and consent events that are logged but not acted on.
Practitioner guidance
- Map the login-to-action gap Inventory where your identity stack grants trust at authentication time but allows sensitive action later without re-evaluation.
- Review OAuth consent and app registration governance Treat consent grants, app registrations, and delegated scopes as governed entitlements with explicit approval, monitoring, and revocation criteria.
- Move sensitive access to action-time checks Apply conditional authorization for privileged or high-impact operations so device posture, location, and behavioural signals are evaluated when the resource is requested.

Centralized identity has become a concentration risk, not just an efficiency layer. When authentication, session control, and delegated authorization all converge in a Mega IdP, the blast radius of a single compromise scales across many downstream services. That changes identity governance from access administration to systemic risk management. Practitioners should treat IdP concentration as an architectural exposure that must be governed like any other critical control plane.
A few things that frame the scale:
- The average organisation believes more than 1 in 5 of their non-human identities are insufficiently secured, according to the 2024 ESG Report: Managing Non-Human Identities.
- 72% of organisations have experienced or suspect they have experienced a breach of non-human identities, with 46% confirmed and 26% suspected.
A question worth separating out:
Q: How should security teams respond when an identity platform is a shared attack surface?
A: They should reduce concentration risk by isolating critical deployments, tightening delegated access, and separating the trust boundary for high-value applications. Shared identity infrastructure should be treated as a systemic dependency, not a neutral utility. The practical goal is to keep one compromise from becoming an enterprise-wide event.
