# kSecAttrAccessibleWhenUnlocked

The data in the keychain item can be accessed only while the device is unlocked by the user.

## Declaration

```swift
let kSecAttrAccessibleWhenUnlocked: CFString
```

## Discussion

Discussion This is recommended for items that need to be accessible only while the application is in the foreground. Items with this attribute migrate to a new device when using encrypted backups. This is the default value for keychain items added without explicitly setting an accessibility constant.
