# Wallets In order to purchase NFTs the user needs to create a crypto wallet. During wallet creation, the user must provide a password to access the wallet later. It is important to inform the user that the password must be written down or otherwise stored since neither PLAY nor developers can recover the wallet password if forgotten. The NFT virtual items are sold for "[rgn-coin](/play-sdk-documentation/sdk-integration-guides/currency-iap.md)" currency. The wallet creation is handled automatically through the OAuth form based on your game requirement. The user will be prompt to create a wallet if needed when trying to signIn. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
