The Shared Vault Trap: Why IAM Programs Fail When Credential Hygiene Stops at the Login Screen
Symptom: Client credentials, API keys, and service tokens live in a shared spreadsheet or a single team vault with no per-user audit trail. Root cause: Teams treat IAM as a login problem and stop at SSO, leaving secrets, service accounts, and machine credentials outside any governed store.

How do you recognize it?
- •Client credentials, API keys, and service tokens live in a shared spreadsheet or a single team vault with no per-user audit trail
- •Offboarding takes days because nobody can confirm which client environments a departing contractor still has keys for
- •Access reviews before a client security questionnaire turn into a manual scramble across four consoles and two password managers
- •A single reused admin password shows up across multiple client tenants, discovered only during an incident or pen test
- •Secrets get pasted into Slack, Notion, or agent prompt files because the sanctioned store is slower than the shortcut
Why does it happen?
- •Teams treat IAM as a login problem and stop at SSO, leaving secrets, service accounts, and machine credentials outside any governed store
- •Unified platforms get bought for the human directory while non-human identities are provisioned ad hoc by whoever ships fastest
- •No owner is assigned to the access lifecycle, so provisioning is automated but deprovisioning stays manual and reactive
- •Client compliance requirements differ per account, and agencies default to the loosest common denominator to avoid per-client configuration work
How do you fix it?
- •Inventory every secret, token, and service account across active client accounts this week and tag each one with an owner and a rotation date
- •Move shared client credentials into a vault with per-user access and event logging, then revoke the spreadsheet and the shared login
- •Wire deprovisioning to your HR or contractor roster so removing a person from the directory closes their client access the same day
- •Run one access review per client retainer before the next renewal and hand the client the export as part of the security conversation
