A single leaked API token can do more damage than most breaches you read about. It can unlock data you never meant to expose, break systems you thought were secure, and put you in violation of GDPR before you even know it happened.
An API token is more than a password. It’s a key that can bypass entire layers of security if stolen. Under GDPR, any personal data accessed through a compromised token counts as a personal data breach. This triggers strict legal obligations: notification within 72 hours, documentation of the incident, and potentially massive fines if compliance fails.
The problem is simple: API tokens aren’t treated with enough care. They sit in code repositories, config files, CI/CD environments, and logs. They expire too late or never at all. They grant broad, unchecked permissions. Developers focus on speed. Security comes later — and later is where GDPR violations live.
The GDPR perspective is clear. Access control must be granular. Authentication must be strong. Tokens must be stored and transmitted securely, encrypted at rest and in transit. Rotation should be a routine, not an afterthought. Audit logs must show where and when tokens are created, used, and revoked. Every token that can touch personal data must be managed as if it’s a potential breach vector.
