I use the swipable Google keyboard and it's generally OK. About 5% of the time an app will use the default Apple one, I think because they're using some kind of secure entry API.

The only problem I have with it is you can't use them for password fields. It would be nice if my password manager could provide a keyboard.

Oh, that is so cool!

LastPass has a "share" action that will autofill - I think that should work regardless of keyboard.

Ah dang. That's something I would really miss from Android (Kepass Keyboard).

It works with Lastpass too!

I use Swype and it seems to work fine. Only every once in a while does it glitch in any noticeable way.
