Trezor always displays the URL of the website the user wants to log in to, and what exactly is going to be authorized therefore it is possible to verify what was sent to the device is the same as what was expected. Phishing protection with on-screen verification.It will never be shared, as it can never leave the device. The recovery seed is safely stored inside Trezor.Allows for an unlimited number of U2F identities, which are all saved under one backup.The recovery seed represents all the private keys generated by the device and can be used to restore the linked wallet at any time. This is a one-time process for all functions of the device. Trezor requires the user to back up the recovery seed during the initial setup of the device.Trezor always uses a unique signature for each and every user account registered.
With Trezor and U2F, the user will have to additionally confirm the login with a click of the button on the Trezor device. When logging into a website, the user generally authenticates himself by providing a username and a password.
Moreover, it is possible to back up a secret (private key). Instead, he has to target individual users, which is much more costly and time-consuming.
When using U2F there is no secret shared and no confidential databases stored by the provider, a hacker cannot simply steal the entire databases to get access. While a backup is theoretically easier, it is not possible for all U2F keys. No personal information shared with private key.No retyping of one-time codes involved.Easier to use than traditional 2 factor authentication.Confidential information is never shared thanks to public key cryptography.Private keys are never sent via the internet.With U2F support in Trezor, it is possible to secure accounts and identities online. The safe characteristics of asymmetric cryptography fall into the security philosophy of Trezor. While initially developed by Google and Yubico, with a contribution from NXP Semiconductors, the standard is now hosted by the FIDO Alliance. Universal 2nd Factor (U2F) is an open authentication standard that strengthens and simplifies two-factor authentication (2FA) by using specialized USB or NFC devices based on a similar security technology found in smart cards.
