# isLocked

A Boolean value indicating whether the document is locked.

## Declaration

```swift
var isLocked: Bool { get }
```

## Return Value

Return Value true if the document is locked; false otherwise.

## Discussion

Discussion Only encrypted documents can be locked. Encrypted documents whose password is the empty string are unlocked automatically upon opening, because PDF Kit tries the empty string as a password if none is supplied. Use the unlock(withPassword:) method to unlock a document using a password.
