The alert fired at 3:14 a.m. and access was locked. No human was involved, but systems still needed a way through. This is where non-human identities break-glass access matters.
Break-glass access is the controlled bypass you use when normal authentication flows fail or are blocked. For non-human identities—service accounts, bots, API keys, automation pipelines—it is more complex. You cannot call them, reset their password, or wait for a ticket to clear. The system needs immediate permission without sacrificing security.
Non-human identities must follow least privilege principles even during break-glass events. When set up wrong, emergency credentials become a permanent backdoor. When set up right, they are time-bound, auditable, and revoke themselves after use.
Best practice starts with defining which roles need emergency elevation. Map every non-human identity to its exact function. This lets you assign temporary privilege that matches the role’s scope. Always log every usage and trigger a review after any break-glass event.
Automate expiration. Static credentials given “just in case” will be abused or forgotten. Use short-lived tokens or temporary role assumption so that break-glass access is granted for hours, not days.
