# accessRef Specifies the initial access controls of imported private keys. ``` var accessRef: Unmanaged? ``` ## Discussion If more than one private key is being imported, all private keys get the same initial access controls. If this field is `NULL` when private keys are being imported, then the access object for the keychain item for an imported private key depends on the [`noAccessControl`](/documentation/Security/SecKeyImportExportFlags/noAccessControl) bit in the `flags` parameter. When that flag is `0` (or `keyParams` is `NULL`), the default access control is used. When the flag is `1`, no access object is attached to the keychain item for imported private keys. --- Copyright © 2026 Apple Inc.
