Alpha characters should be ignored

[Myoldmopar]

From the PIN entry, it seems like this should only accept numeric values. However, the keyboard entry allows the user to enter letters and numbers.

I just did a test:

• PIN_PASSCODE_PIN specified as "251c"
• Entered the page and typed 2 5 1 c , and that sequence showed up but did not let me log in

I think maybe alpha characters should just get ignored upon keyboard entry? And maybe when the passcode is being read in from environment or settings, an error should be thrown for any non-numeric characters? Or, maybe alphas are allowed and I'm just missing something. Definitely possible! 🙃
