This source code fully belongs to devinmartin.
This repository is a reupload of his repository on bitbucket, because his repository is no longer available there.
(The original repository can be found here.)
Because the repository of devinmartin went down, I continued the plugin and renamed it to KeeOtp2.
Devinmartin released the KeeOtp plugin under the MIT license.
