Bottom line: Separate contact-group permission to use a stored credential from full edit/delete rights, and treat the colocated site obfuscation key as protected recovery material rather than a password-safe boundary.
\nThe Checkmk password-store guide separates the right to store a credential from the right to use it through contact groups. Editable by grants full use, change and deletion rights, while Share with adds contact groups permitted to use the credential. During ordinary selection, the stored password is represented by its title rather than displaying the password value. The guide explicitly calls the store obfuscation rather than a password safe: Checkmk needs plaintext access, and the file-encryption key is stored within the site directory.
\nThis article reviews the guide’s user-permission and site-custody boundaries. It does not claim that hiding a password in the selector protects it from every administrator or filesystem reader, or approve a particular secret-retention policy.
\nThe following steps are DSE recommendations based on the cited source.
\nDSE recommends a credential-access matrix with separate use, change and deletion columns. Name the owner and intended consumers before choosing contact groups. Review the selected groups’ actual membership rather than relying on a familiar group title or treating permission to use a credential as a request for full administration.
\nGive the entry a meaningful nonsecret title and preserve a controlled reference to the external account. Keep actual values out of screenshots and tickets. Ask another operator to identify the correct entry by that title before assigning it to a monitoring rule, especially where several credentials serve similar endpoints.
\nReview site-level file and recovery access separately from the GUI permission matrix. Include the credential data and associated key in the organization’s protected-material handling plan. Do not advertise the password store as an independent vault boundary merely because ordinary selection hides the value.
\nFor a proposed credential change, identify the rules and service owners that must validate use afterward. Keep unrelated privilege changes outside the rotation exercise. Prepare a harmless authorized test operation and a recovery decision for a failed use, without broadening the contact groups solely to make the operation succeed.
\nProposed verification: use a disposable credential and approved test identities representing use-only and full-edit requirements. Compare the available selection and management operations with the written matrix. Retain entry identifiers and actual permission results without printing the credential itself.
\nPerform the agreed harmless monitored operation through the intended rule and inspect its actual result. Have the owner review site-file custody independently of that successful use. Record denied or unexpectedly available management actions as access findings, and remove the disposable credential through its approved lifecycle procedure.
