Bellow you can find the noob guide on what to do after purchase 😀
After loging in to steam, the first thing you want to check is the family view button. If it is ON make sure to disable it, although some accounts might have it disabled already. Proceed with email and password change, it is important to first change email then password, not the other way around. After completing first 3 steps, add another layer of security to your account by turning either email or mobile steam guard on !
