Android WordPress App Blocks Login with iThemes Security

I have an Android phone with the WordPress app on it (latest version, 3.9). Since I installed iThemes Security I have been unable to log in to my self-hosted blogs using the Android app. It keeps saying my password is wrong, even though I am 100% sure it is correct. At first I thought it had to do with the login slug being changed (wp-login is now /kennylogins instead) but when I deactivated that feature it still wouldn’t work.

Anyone else experience this? I find it hard to believe that one has to choose between using iThemes security and using the Android app. That would just be ridiculous.
