The picture of the lock and related password fields are relatively low and off centered in landscape mode on iPad (shown in attached screenshot). Maybe pushing it up a bit will make it seem more balanced.
I'm guessing we have a bug for when the keyboard is hidden, it didn't center it properly. If you rotate the device, it shows up centered in portrait mode and if you bring up the keyboard in the landscape mode, it is centered properly as well.
We'll get this fixed, thank you for reporting this!
Not sure if it's been fixed yet, but in the latest beta I noticed the problem is still there.
