Instead of using PuTTY to run Cygwin, try using mintty instead.  It is
available as a Cygwin package and is originally based on some fork of
PuTTY if I recall correctly.  Using a standard Windows cmd terminal will
also work.

I believe the problem is that Cygwin programs, such as git, expect to
have a terminal when they prompt for passwords like that.  Cygwin
programs don't understand PuTTY as a terminal though.  They probably see
it as a plain pipe, so they won't try to treat it like a terminal and
will thus be unable to capture passwords like this.

You can see similar problems for native Windows programs that try to
take input in a similar manner when running in a terminal such as
mintty.  Again, they see the terminal as a simple pipe, so it's
impossible to do any of the terminal magic necessary to capture the
password silently.
