If you purchased Playstation Game Account here are tips how to use and customize the account:

1. Use the credentials you received (directly or via an external website) and log into the account. 
2. Make sure that the content on the account is correct (correct edition of the game, no playtime etc)
3. Add the purchased account to your console and set it as a primary one. Purchased account has to be added as a user, not as a one-time guest
4. Change the credentials to make the account your own:

• Change the email
• Change the password
• Add 2FA

5. Once the account is added to your console (as a primary one), download the game and switch back to the account you would like to play from. This way your progress will be saved on the account you are using. 
6. The account should be used as a way of accessing the game/content you are interested in. It is not recommended to use it as your main account, as you might have issues with making purchases on it.

In case of any issues with the account you can contact a seller/Kinguin Support via the Resolution Center using the following link.
