I now thought, is it possible to create such a project that will automatically register my computer (for example) on sites, and automatically go there under my login. Those. so that when entering any site that requires a login (for example, the same Habra) from my computer, it automatically loads my data from somewhere (for example, from the OS) and logs in automatically. Or, when I first visited this site, something like “Do you want to register on this site?” Was requested, and if I agree, the same data would be taken from the OS and automatic registration would be performed. It turns out like a universal OpenID. Or maybe this already exists?
