So long time ago people started thinking about password-less login, this is a big ...

  Do we need other languages other than C and C++?

There were hundreds of or thousands of programming languages created since the invention of computer. All these languages have the same target which is to make the computer do what we want it do. So we may find that many languages have the same functions, i.e, one task can be completed by one language can be completed by another language as well.
