What security features does Ledger offer?

Ledger provides a comprehensive suite of security features designed to protect users' cryptocurrency assets. One of the primary components of Ledger's security architecture is its use of a secure element, which is a tamper-proof chip that securely stores sensitive information, such as private keys. This secure element is designed to resist physical and software tampering, providing a robust layer of security against unauthorized access. In addition to the secure element, Ledger employs an operating system called BOLOS, which is purpose-built for the secure management of applications. This operating system ensures that applications run in isolated environments, thereby preventing malicious software from affecting the overall device. Each application within the device is separately sandboxed, adding an extra layer of protection. Ledger also incorporates a recovery phrase, which consists of a series of words generated when the device is set up. This recovery phrase serves as a backup, allowing users to restore their assets if the device is lost or damaged. Users are encouraged to store this recovery phrase in a safe location. Further enhancing security, Ledger provides users with the option to set a PIN code, which must be entered each time the device is accessed. Additionally, users can enable two-factor authentication for added protection. Overall, Ledger’s multi-layered approach ensures that users' digital assets remain secure in a pairing of software and hardware that emphasizes both user convenience and security.
