Your password is not enough. Even a strong, unique password can be compromised through data breaches, phishing, or keyloggers. Two-factor authentication (2FA) adds a second layer \u2014 and for crypto, it is not optional.<\/p>\n
2FA requires two different proofs of identity to log in: something you know (your password) and something you have (your phone, a hardware key, etc.). Even if an attacker steals your password, they cannot access your account without the second factor.<\/p>\n
A code is sent to your phone via text message. This is better than nothing, but it is the weakest form of 2FA.<\/p>\n
Why SMS is dangerous for crypto:<\/strong> SIM swap attacks. An attacker convinces your phone carrier to transfer your number to their SIM card. They then receive all your SMS verification codes. This attack is well-documented and has been used to steal millions in cryptocurrency.<\/p>\n An app on your phone generates a new code every 30 seconds. The code is created on your device, not sent over the network. Common options include Google Authenticator, Authy, and Microsoft Authenticator.<\/p>\n This should be your minimum standard for all crypto accounts.<\/strong><\/p>\n A physical device (like YubiKey) that you plug into your computer or tap against your phone. It is phishing-proof because it verifies the website is legitimate before responding.<\/p>\n This is the strongest form of 2FA available. If you hold significant crypto, consider investing in one.<\/p>\n 1. Download an authenticator app (Google Authenticator or Authy)<\/p>\n 2. Go to your exchange\/service security settings<\/p>\n 3. Select “Authenticator App” (not SMS)<\/p>\n 4. Scan the QR code with the app<\/p>\n 5. Write down the backup codes on paper<\/strong> \u2014 if you lose your phone, these are your only way back in<\/p>\n 6. Verify with one code to confirm setup<\/p>\n If you use Google Authenticator and lose your phone without backup codes, you are locked out of your accounts. Recovery can take weeks or be impossible.<\/p>\n Always save backup codes on paper in a secure location.<\/strong> Treat them with the same care as your seed phrase.<\/p>\n 2FA protects your online accounts. Cold storage protects your long-term holdings. Together, they cover most attack vectors.<\/p>\n \ud83d\udee1\ufe0f Get Tangem Wallet<\/a><\/strong> \u2014 Cold storage for your assets.
