Steps

1. 1Download an authenticator app: Authy, Google Authenticator, or Microsoft Authenticator.
2. 2Log into your exchange and navigate to Security or Account Settings.
3. 3Select 'Enable 2FA' or 'Authenticator App' and scan the QR code with your app.
4. 4Enter the 6-digit code from the app to confirm setup.
5. 5Save the backup/recovery codes in a secure offline location.
6. 6Repeat for every exchange and crypto service you use.

Pro Tips

• Authy offers encrypted cloud backup — if you lose your phone, you can recover codes. Google Authenticator does not.
• For maximum security, use a YubiKey (hardware key) as your primary 2FA and the app as backup.
• Disable SMS-based 2FA if possible — it's vulnerable to SIM-swap attacks.
