BOLOS is designed to protect against malicious attacks by isolating applications from each other on a device. In 2016, the company created the Blockchain Open Ledger Operating System (BOLOS) which-according to Gauthier-combines the “best features” of smartcard chip technology witnessed in both passport and credit card systems. Ledger has developed a reputation for security over the years. “As all user private keys and public addresses arise from the master private key, you can manage many accounts or assets with a single device.”

“When a user sets up their device, a unique master private key is created by Ledger’s secure hardware and software,” Gauthier explained. From there, 2FA is activated and a user will need to log into the attached account using both their password and their Ledger device, thereby adding an extra layer of security. Here’s how it works: To get started with the app, users must first download Ledger Live -an online system built for managing cryptocurrencies-and install it onto their devices by selecting the FIDO U2F app in the “manager” section.Ĭheck out our selection of the best crypto wallets (2020 update).Īfter installation, users then select the compatible services-which include Google, Dashlane, GitHub and others-that they’d like to attach to their devices and enhance with two-factor authentication. “They belong to service providers, so the control of the account always remains with a company.” “Your phone number or your email is not something you really own,” he said. CEO of Ledger Pascal Gauthier explained to Decrypt that while many accounts invoke their own two-factor authentication protocols, several rely on email or text (SMS) verifications to complete one’s access, which are not the most secure options.
