There is a minor issue in the login screen of SplashID Safe iOS app on iOS 8. When switching between the ABC and 123 input methods, the keyboard doesn't update on the switch as it should. We are going to fix this asap. 

In the meantime, there is an easy workaround... If you need to switch input methods, say ABC to 123, tap the Pattern input tab first, then tap 123. Then tap the password field and it will refresh with the correct keyboard.

If you need to enter mixed input, keep your input set to ABC, and use the bottom left button on the keyboard to switch to numeric input as needed.
