Most common questions concerning 2FA
What is 2FA and how it works?
Two-Factor Authentication (2FA) as its name suggest, adds another layer of security to your accounts by making sure that the login procedure involves something that only you would own on yourself, additionally to your user ID and password. This additional information could be a code received by SMS or by email, a code provided by the Google Authenticator application or an action on your favorite hardware wallet.
Why is 2FA important?
By adding one more step when authenticating your identity, you are making it harder for an attacker to access your data. This drastically reduces the chance of fraud, loss of data, or identity theft. In a world of digital crime, with hacking and fraud on the internet on the rise, there’s never been a better time to safeguard your information with an extra level of security. Particularly for cryptocurrency investors who require state-of-the-art security to protect their funds.
Ledger, an Associate member of the Fido Alliance
Ledger is an Associate member of the FIDO alliance, thanks to Nicolas Bacca, co-founder and CTO of Ledger, who designed the 2nd commercial U2F implementation for Plug-up/Happlink and has been involved in the embedded security industry for more than 15 years. Our Ledger U2F application is FIDO Certified and open-source. The 24-word mnemonic phrase generated at setup also backups the U2F user identity, safeguarding losing your device or it malfunctioning. The U2F identity is also protected by the device PIN, providing a layer of protection when using U2F to authorize critical actions.
Finally, Ledger is working on the implementation of the next generation FIDO standard (FIDO2) to support the Transaction Authorization extensions to use the trusted display of the device to validate critical data and securely enforce the user validation of this critical data end-to-end.
