 Note: A [private key](https://en.bitcoin.it/wiki/Private_key) (xprv) is **never** required for receiving money to a BTCPay wallet. The software needs a public key (xpubkey) which is a watch-only wallet token. The xpubkey allows BTCPay to generate a new address each time a new invoice is generated. It enables users to observe the wallet balance and transactions without having to share their private key.
 
-*The wallet does not generate a private key. Users have to create their own private key externally and import an xpubkey derived from the private key into Store Settings > Derivation scheme.  The public key (xpubkey) can be imported from a compatible hardware wallet or added manually by pasting the key into the field and adding an appropriate suffix. For more information on how to add a derivation scheme to BTCPay, see the [Getting Started Guide](GettingStarted.md). If you're using a [third-party host](ThirdPartyHosting.md) and are asked to provide a private key, it's certainly a scam. Never share your private key with anyone. It's called private for a reason.*
