Security & Scams
How to Secure Your Crypto Account: 2FA and Beyond
Almost every hacked account has one thing in common: incomplete security settings. The 6 protections to enable right after sign-up, in order, and what to do in case of intrusion.

2026 action checklist
- Use app- or hardware-based 2FA rather than SMS alone.
- Enable an anti-phishing code and a withdrawal-address whitelist.
- Store recovery codes offline and review active sessions regularly.
Exchange platforms are heavily attacked — but in practice, almost every individual account takeover exploits the user's missing settings, not the platform itself. Six protections, enabled once, eliminate the vast majority of realistic attacks. Here they are, in the order you should activate them.
1. A long, unique password
Unique means used nowhere else. Most account takeovers start with a password reused on a site that got breached. Use a password manager; length beats complexity — aim for 12+ characters.
2. App-based 2FA — not SMS alone
SIM-swap fraud makes SMS the weakest second factor. Install an authenticator app (Google Authenticator, Aegis, etc.) and bind it to your account.
Critical detail: when the app shows the setup key, write it on paper. Lose your phone without that backup and account recovery becomes a slow support process.
3. The anti-phishing code
A personal word or phrase that OKX then includes in every genuine email. Any "OKX" email without your code is fake — instantly, without inspecting links. It costs 30 seconds in security settings and defuses the most industrialized attack out there.
4. The withdrawal whitelist
Restrict withdrawals to pre-approved addresses, with a time delay on additions. Even a fully compromised account cannot drain funds to an attacker's address without waiting through the delay — time you use to react.
5. Device hygiene
- Install the official app only; bookmark the website rather than clicking search results or chat links.
- Keep the OS updated; avoid trading from shared or public computers.
- Never enter credentials after following a link someone sent you — type the address or use the bookmark.
6. Fund segregation
Security includes limiting the blast radius. Keep active trading funds on the platform; move long-term holdings to storage suited to the amount — the trade-offs are covered in crypto wallet or exchange.
If you suspect an intrusion
- Freeze the account immediately (OKX offers a one-tap account freeze in security settings, and support can do it too).
- From a clean device, change the password and re-bind 2FA.
- Review withdrawal addresses, API keys and connected devices; remove anything you don't recognize.
- Check your email account security too — it is the recovery hub for everything else.
