A private key is like a password — a string of letters and numbers — that allows you to access and manage your crypto funds.

Manage your private keys. Ledger hardware wallets enable easy and secure private key management. When you set up your device, a unique set of private keys is created by Ledger’s secure hardware and software. These private keys allow you to manage many accounts and crypto assets from a single device.
