Good thing is that website or web application will prompt you to allow it to use this feature like when a site/application wants to use your microphone or web camera. Developers are on board with this feature since it can provide them with more telemetric data on how users are interacting with their website/application but there are some that are strongly voicing against this.

Windows will then go to the accounts settings page. Within that page, click on the Family & other users to open the setting for the chosen section on right. On the right settings, screen navigate to the lower section and click once with the left button on add someone else to this PC
When add someone else to this PC is clicked, pop up window will appear which will ask you to provide the persons email address and later on the password of his/her Microsoft account, after the required information is provided you are done, a new user has been added and he can use his Microsoft credentials on the login screen to use this computer.
This will open yet another pop-up giving you the option to create a Microsoft account for this person, to use a phone number instead of a Microsoft account, or to create a new email address for the user. Any of these options will create a new user for this computer with provided credentials but there is the last option at bottom of the pop-up which will allow you to create a local user only without a Microsoft account. This user will be able to use this computer, will not be able to transfer his document through various devices like he/she would if using a valid Microsoft account but it could use the computer and personalize it fully to his/her liking.
Once the link is clicked, you will be presented with a floating window requiring you to input needed information in order for the account to be created. You will need to provide username, password, and answers to 3 security questions.
Once all information has been provided, click on next and your new non-Microsoft local user has been created. Now when you click on Family & other users you will see that Windows has added a new user with the provided name to this computer. If you wish, you can add another user in the same manner, following the previous steps. Microsoft Windows does not have a limit for how many users can be on one computer so feel free to create as many as you like.
Click on Change account type.
Under account type, you will have the option to promote this user to an administrator if you wish or you can leave it as a standard user.
