Claude API key stopped working when someone left? Personal vs service account keys

Ship ItChecked against the official source

The short answer

Since November 2, 2026, you can create personal keys and service account keys in the Claude Console. Claude's Authentication docs: when that identity is removed from the organization, the key stops working. A shared personal key acts as one person and breaks when they leave. For shared or automated workloads (CI, production services), have an organization admin create a service account so the workload has its own identity.

What to do

  1. Use a personal key for your own development and scripts.
  2. For your app in production, ask an organization admin to create a service account, then create a key with the service account as the linked account.
  3. In the Claude Console, keys are created on the API keys page: name the key, choose an expiration and set Linked account.

Good to know

  • Workspace API keys still work but should be considered legacy.
  • Personal keys and service account keys have the same permissions as the account they belong to.
