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. ## What the source does not establish This 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. ## Applicability questions - Which contact groups need credential use, and which need full editing rights? - What title and controlled credential reference identify the intended entry? - Who can access the site’s credential file and obfuscation key? - What separate application operation will demonstrate authorized use? ## DSE recommendation: controlled next steps The following steps are DSE recommendations based on the cited source. DSE 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. Give 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. Review 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. For 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. ## Verification and evidence Proposed 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. Perform 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. ## Official references - [Checkmk — Password store](https://docs.checkmk.com/latest/en/password_store.html) — official product documentation; confirm the installed release and configuration.
