Simulation of authorization through LocalStorage?

Question

JavaScript

Hey! Please tell me how it is possible and if it is possible to implement an imitation of user authorization through LocalStorage: the user enters a login and password in the form, after submitting the form, his data gets into LS, then from the authorization page there is a redirect to another page, where in the header (for example, top panel) will display the same login of the current user.

Thanks in advance to all who respond!
