Migrate an existing nansen-cli wallet from insecure password storage (env files, .credentials) to the new secure keychain-backed flow.
Use when SecItem calls fail — errSecDuplicateItem from unexpected uniqueness, errSecItemNotFound despite item existing, errSecInteractionNotAllowed in background, keychain items disappearing after app update, access group entitlement errors, or Mac keychain shim issues. Covers systematic error diagnosis with decision trees.
Rotate an API key or secret across all locations — local .env files, macOS Keychain, GCP Secret Manager, Kubernetes deployments, and Codemagic CI. Use when: 'rotate key', 'update key', 'key leaked', 'replace secret', 'new API key', 'update GEMINI key', 'rotate secret'.
Use when storing credentials securely, encrypting data, implementing passkeys, code signing, or managing certificates and provisioning profiles.
