How to work with another account in vk?

Question

PHP

Let's say there is a page with a login and password form from VK.
How to make it possible to work with api vk exactly from the account whose password and login will be entered in this form?
I would be grateful for the article and help here ... I apologize in advance for the wording, I can not correctly formulate the problem concisely and correctly.
Thanks in advance.

Pages with such forms do not need to be done!!!
Do authorization through vk api, the documentation is very detailed and understandable.
And read the list of methods, it is possible to get a list of friends / photos / audio recordings of a user by his id (which will become known to you after authorization via api).
