S5 Fingerprint scanner and alternative password on lock screen.

[Majkelo77]

Hello everyone!

I would like to ask you if it's possible to change the alternative password for fingerprint scanner to a PIN code? Just like iOS style.

It seems a little bit annoying when you have to put your password quite often.

And if it's impossible... How can we hide letters that we type. I do not want them to be visible for a few seconds.
