Analyze the security risk of OAuth 2.0 scope combinations. Evaluate token lifetimes, data sensitivity, and scope permissions to identify potential vulnerabilities in your authorization configurations.

OAuth 2.0 scopes define what resources an application can access. Poorly configured scopes create security vulnerabilities—overly permissive tokens, long lifetimes, and sensitive data access combine to increase attack surface. Our calculator helps you quantify and visualize these risks before they become breaches.
OAuth scope risk measures the potential security impact of granted permissions. Each scope carries a base risk weight (1-10) that gets amplified by token lifetime, data sensitivity, and total scope count. A token with admin access to financial data that never expires presents catastrophically higher risk than read-only profile access with a 1-hour lifetime.
Risk Calculation
Risk = Σ(Scope Weight × Duration × Sensitivity × Count Penalty) / Max Risk × 100Identify unnecessary scopes that violate security best practices. Request only the permissions your application actually needs.
Understand the blast radius if tokens are compromised. High-risk configurations mean stolen tokens cause more damage.
GDPR, SOC 2, and other frameworks require documented risk assessments for data access. Quantify your OAuth security posture.
Evaluate OAuth permissions requested by third-party apps before granting access to your systems.
Design your authorization flows with risk visibility. Choose appropriate token lifetimes based on scope sensitivity.
When designing your OAuth server, evaluate default scope combinations and token policies. Ensure clients can't request dangerous combinations.
Before connecting a third-party app via OAuth, assess the risk of requested scopes. Many apps request more permissions than they need.
Document the risk profile of your OAuth integrations. Identify high-risk configurations that require additional monitoring or controls.
Configure scope validation rules based on risk thresholds. Block or flag requests that exceed acceptable risk levels.
Help developers understand why certain scope combinations are problematic. Visualize the risk amplification of poor token policies.
Prioritize token revocation efforts based on risk scores. Focus on high-risk tokens first during security incidents.
Scopes that grant write access, admin privileges, or access to financial/personal data carry the highest risk. The risk compounds when combined with long token lifetimes and sensitive data classifications. Admin + delete + indefinite tokens represent maximum risk.
