Remove value of a certain key

[jakemonton]

I would like to remove values for my email address and password values to null, but how can I reset it into null values or an empty string?

I thought there's method for removing values or for a certain key.

I have only android code to remove a preference. You can make a pull request to add cordova call for key removal.

But I don't understand your use case. If you don't want to store something in preferences, just don't store it.
