Give another option to use built-in qrcode generator rather than using Google service

arafatx

I look into 2 step authentication post output and saw DA was trying to fetch an OPT qr code by providing sensitive information to google via query:

maybe DA can give us a choice whether to use a built-in otp qr code generator or use it from Google.

I notice also, the chart is actually a deprecated API. Should we remove this?

What do you think about this?
