It is asking me for login too & I tried 3 different browsers on my laptop to confirm this.You may be having some saved aliexpress account in your browser settings/some addon.If you look at the link carefully you will notice that it is not usual aliexpress link & it has "wholesale" included in link text which indicates it may have been a wholesaler product link & not your usual seller link which is probably why it is asking for login.The link is opening fine for me, without any need to sign in.
