# ODRecordSetNodeCredentials(_:_:_:_:) Sets node authentication credentials for a given record. ``` func ODRecordSetNodeCredentials(_ record: ODRecordRef!, _ username: CFString!, _ password: CFString!, _ error: UnsafeMutablePointer?>!) -> Bool ``` ## Parameters `record` The record. `username` The username to use to authenticate with the node. `password` The password to use to authenticate with the node. `error` An error reference for error details. Can be `NULL`. ## Return Value `true` if the credentials are successfully set; otherwise, `false`. ## Discussion If you want to set credentials for all references to a node, use [`ODNodeSetCredentials(_:_:_:_:_:)`](/documentation/OpenDirectory/ODNodeSetCredentials(_:_:_:_:_:)) instead. If this function fails, the previous credentials are used. --- Copyright © 2026 Apple Inc.
