# profileIdentifier

An optional identifier for the current browsing profile.

## Declaration

```swift
var profileIdentifier: STWebHistory.ProfileIdentifier? { get set }
```

## Discussion

Discussion The default value is nil. This identifier represents a profile and allows you to keep your browsing separate for topics like work, personal, or school. Using nil will report web history without a profile identifier. Web browsers with a “default” profile may want to use nil in order to match any web history reported prior to this API.
