Retries and backoff for security services

TLS, authorization, request integrity, caching and network failures.

Network and API protection1 min readEditorial methods

Uncontrolled retries can worsen temporary failures. Design mobile verification retries within a total latency budget.

Evaluation approach

Set timeouts, bounded attempts and distributed delays. Ensure retries cannot duplicate operations.

Application example

Staggered waiting can reduce a second load wave when many devices retry simultaneously.

Limits and considerations

Invalid credentials or signatures should not be retried indefinitely as transient network failures.

Which errors should not be retried?

Treat permanent authorization rejection and invalid signatures differently from timeouts. Tie retries to error classes instead of showing an endless spinner.

Checks and decisions

  • Classify errors
  • Bound attempts
  • Measure total delay
