+### Access restricted KWICs
+In order to perform the collocation analysis and other textual queries also on corpus parts where KWIC access requires a login, you need to authorize your application via an access token.
+
+In the case of DeReKo, you cat get an access token from [KorAP OAuth settings here](https://korap.ids-mannheim.de/settings/oauth#page-top). There login, register a new client application, create a new token, copy it and in R use it via the `accessToken` parameter:
+
+```
+kco <- new("KorAPConnection", accessToken="<access token>")
+```
+
+You can also persist the access token for subsequent sessions with the `persistAccessToken` function:
+```
+persistAccessToken(kco)
+```
+
