币界网报道：Ledger has introduced Recovery Key, a physical backup solution for its Ledger Flex and Stax wallets, enabling users to quickly regain access by tapping an NFC-enabled card and entering a PIN. The offline backup key, which works alongside traditional 24-word seed phrases, leverages the same secure element technology used in Ledger devices. The company emphasized the optional nature of the feature, noting users can create multiple keys directly on their wallet devices. Ledger's Chief Experience Officer Ian Rogers stated the product aims to simplify secure self-custody, offering alternatives to exchanges and software wallets. This follows Ledger's 2023 Recover service, which stores encrypted seed fragments across jurisdictions. The new solution has undergone security testing by Ledger's internal white-hat team and external audits, with its code and whitepaper publicly available. The Paris-based firm, which has sold over 7.5 million devices, plans to release Recovery Key soon while maintaining user control over recovery options.
