Top 10
This is an account, not a key
With this offer you get the login data of an account that someone else created. The game stays on that account and never belongs to you.
The platform can lock such an account, for example because the resale of accounts breaks its terms of use. You then lose access to the game.

Is it safe to buy from key shops?
Key shops are retailers or marketplaces on which other sellers also offer keys. Before you buy, read the product page of the shop: it shows the region, the platform and the type of the offer. A payment method with buyer protection gives you more security if a problem occurs.
Key, gift or account?
A key is a code that you redeem yourself in the platform client. You accept a gift through your account, often with a region lock. An account gives you the login data of an account that holds the game, and the game does not belong to you. For this reason, the product type filter does not show accounts by default.
