# profileIdentifier

An optional identifier for the current browsing profile.

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

## 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.
