Choosing an exchange · Lesson 3 of 3
Lock down your account
Turn on two-factor authentication with an authenticator app. SMS codes can be stolen through SIM-swap attacks.
Set an anti-phishing code, so real emails from the exchange always show your secret word.
Use a unique password and, if offered, a withdrawal whitelist, so money can only go to addresses you approved.
Key points
- Authenticator 2FA, not SMS
- Anti-phishing code on
- Withdrawal whitelist if available
Education only, not financial advice. Crypto is risky — only use money you can afford to lose, and check it’s legal where you live.
