After purchasing this product, you will receive a login and password for the account. You can play on this account during the rental period. You can add friends to the account. I am a novice seller, so if there are any inconveniences or problems, I apologize in advance. If you suddenly cannot add someone as a friend for some unknown reason or may have some problems, then follow this link in the browser: https://steamcommunity.com//friends/add enter the login and password for this account (if you were in your account before, then log out of it and go to the purchased one), then enter the friendship code of the person you need to add as a friend, his mini profile will appear, but you cannot send an invitation due to steam restrictions (the button will be gray), so you need to click on the button on the left (link to the profile), go to the profile, click on add to friends, after which the invitation to friends should be sent. This is a detailed guide, if suddenly someone did not know about this method, I wrote it so that no one would have problems, because I only want the best attitude towards my customers
