Using Windows 10 without login or Windows 10 without password comes with risks of its own. However, if you are using a PC at home with no one else passing by the system and consider removing the login password, the procedure for the same is as follows:

Press Win+R to open the Run window. Type the command Netplwiz and press Enter to open the User Accounts window.
Uncheck the box next to "Users must enter a username and password to use this computer." Select Apply and then OK to save the settings, and then restart the system.

Note: This doesn't work with some computer brands since the manufacturers have designed them such. Furthermore, certain group policies on your system might also prevent the same. Please contact the IT administrator in such a case.
