Spring Security Rate Limits

Spring Security is a self-hosted authentication and authorization framework — there is no vendor-hosted API and therefore no vendor-imposed throughput limits. Spring Authorization Server (a Spring Security sub-project) ships token endpoints whose throughput is bounded only by the operator's deployment. Throttling is added by the surrounding gateway, Resilience4j, or a custom filter.

Spring Security Rate Limits is the machine-readable rate-limit profile for Spring Security on the APIs.io network, conforming to the API Commons Rate Limits specification.

It captures 1 rate-limit definition, measuring varies.

The profile also includes 2 backoff/retry policies defined and response codes documented for throttled.

Tagged areas include Authentication, Authorization, Java, OAuth2, and Spring Framework.

Limits

Operator-Defined deployment
varies
see operator deployment configuration
Spring Security and Spring Authorization Server emit no built-in throttling. Effective limits depend on the gateway, ingress, or filter chain in front of the OAuth2 endpoints.

Policies

Self-Hosted Throttling
Operators commonly add a Servlet or WebFlux filter (often Resilience4j-backed) that emits 429 with Retry-After when the token endpoint is hammered. Spring Security itself does not enforce a request rate.
Lockout vs Throttle
Spring Security distinguishes account-lockout policy (UserDetailsService / failed-login counter) from request-rate throttling. Lockout is per-principal; throttling is per-IP or per-key and lives in the surrounding stack.
