Implementing JWT Refresh Token Rotation for Video API Clients in PHP 8.4

Short summary

Leaked refresh tokens grant attackers up to 30 days of silent API access under traditional schemes. Token rotation organizes tokens into families where each redemption invalidates the old token and issues a new one. If any token is reused, the entire family revokes, turning silent compromises into detectable incidents; this guide covers the SQLite schema, incident-response signals, and PHP 8.4 implementation for production.

• •Static refresh tokens are a critical vulnerability: a leaked token grants 30 days of undetected API access
• •Token rotation with family-based tracking makes every token single-use while maintaining a lineage
• •Reuse detection revokes the entire token family, immediately surfacing compromises instead of silently persisting
