How to Keep Your #Bitcoin Safe From Phishing and Brute Force Attacks?

Make sure to use a Yubikey Security Key

How It Works?

It enhances the security of both hot and cold wallets by providing robust authentication mechanisms. For hot wallets, which are frequently used and connected to the internet, the Yubikey can be employed for two-factor authentication (2FA) using Yubico OTP or FIDO2/WebAuthn, adding a strong layer of security against hacks and phishing attacks. 

Yubikey engages a Challenge-Response to ensure that only the legitimate user can authenticate. Services that support OATH-HOTP can also leverage the Yubikey to generate time-based or event-based one-time passwords, providing another layer of security.

For cold wallets, which are offline and used for long-term storage, the Yubikey can secure access to the software managing the cold wallet, such as Ledger Live or Trezor Suite, using FIDO2 for protected login.

Additionally, the Yubikey can help protect backup and recovery information by encrypting files containing recovery phrases or private keys, with the Yubikey serving as the decryption key.
