Why can't I log in with my text pin after upgrade to Preview 10?

[Windows Central Question]

can not log in with my text pin after upgrade to Preview 10

I had a text PIN Login on my Lumia 930 (via standard letter keyboard)
After installing the Windows 10 Mobile Insider Preview only a Number PIN Pad for entering a PIN is popping up?!

How can I now log into my Phone again??
