Most crypto theft doesn't happen through clever hacking — it happens because someone reused a password, skipped two-factor authentication, or clicked a phishing link. This guide covers the specific, actionable steps that protect your exchange accounts, wallets, and associated email.

💡
If you're earning crypto on RentAHuman, your wallet and linked accounts are directly tied to your income. Securing them isn't optional — it's protecting your paycheck.

Step 1: Two-Factor Authentication (2FA)

2FA means that logging in requires two things: your password and a time-based code from a second device. Even if someone steals your password, they can't get in without that second factor.

Use an Authenticator App (Not SMS)

SMS-based 2FA sends codes via text message. The problem: SIM swap attacks. An attacker calls your phone carrier, convinces them to transfer your number to a new SIM, and receives all your 2FA codes. This isn't theoretical — it's happened to thousands of crypto users.

2FA methods ranked by security
🟢 Hardware security key (YubiKey)  — Best. Physical device required.
🟢 Authenticator app (Authy, Google) — Great. Time-based codes on your phone.
🟡 SMS text message                  — Okay. Vulnerable to SIM swaps.
🔴 Email-only                        — Weak. Email accounts get compromised.
🔴 No 2FA                            — Dangerous. Don't do this.
  • Recommended apps: Authy (has cloud backup), Google Authenticator, or Microsoft Authenticator.
  • Back up your 2FA: when you set up 2FA, the service shows a QR code or secret key. Save this backup code somewhere safe — if you lose your phone, you'll need it to regain access.
⚠️
Enable 2FA on your exchange accounts, email, and any platform connected to your finances. Do it now. Literally right now, before continuing this article.

Step 2: Password Hygiene

Your passwords are probably worse than you think:

  • Use a password manager — Bitwarden (free and open-source), 1Password, or LastPass. Generate a unique, random password for every account.
  • Never reuse passwords — if your password for a random forum gets leaked (it happens constantly), and you used the same password for Coinbase, your crypto is gone.
  • Make your master password strong — the password for your password manager should be long (16+ characters), memorable, and not based on personal info.

Check if your email has been in a data breach at haveibeenpwned.com. If it has, change the password immediately for any account using that email + compromised password.

Step 3: Secure Your Email

Your email is the skeleton key. Password resets for exchanges, wallet recovery, and 2FA changes all go through email. If someone gets into your email, they can reset everything.

  • Enable 2FA on your email account (Google, Microsoft, ProtonMail all support it).
  • Consider using a dedicated email address solely for crypto exchanges — not the one you use for newsletters and social media.
  • If you use Gmail, enable Google's Advanced Protection Program for the strongest possible account security.

Step 4: Hardware Wallets for Larger Holdings

For holdings above $1,000, a hardware wallet (Ledger Nano, Trezor) is the gold standard. Your private keys never touch the internet, so even if your computer is fully compromised, your funds are safe.

Step 5: Exchange-Specific Settings

Most major exchanges have security features that users never enable:

  • Withdrawal address whitelist — only allow withdrawals to pre-approved addresses. Even if someone gets into your account, they can't withdraw to their own wallet.
  • Anti-phishing code — Binance and others let you set a custom word that appears in every legitimate email from them. If the word is missing, the email is fake.
  • Login notifications — get alerted when someone logs into your account from a new device or location.
  • API key restrictions — if you use API keys (for trading bots, etc.), restrict them to specific IPs and disable withdrawal permissions.

The Complete Security Checklist

Crypto security checklist
Exchange Accounts:
  ☐ Authenticator app 2FA enabled (not SMS)
  ☐ Unique password via password manager
  ☐ Withdrawal whitelist enabled
  ☐ Anti-phishing code set
  ☐ Login notifications on

Email:
  ☐ 2FA enabled on email account
  ☐ Strong, unique password
  ☐ Dedicated email for crypto (optional but recommended)

Wallets:
  ☐ Seed phrase backed up on paper/metal in 2 locations
  ☐ Seed phrase NEVER stored digitally
  ☐ Hardware wallet for >$1K holdings
  ☐ Old token approvals revoked (revoke.cash)

General:
  ☐ Password manager installed and populated
  ☐ Official sites bookmarked
  ☐ Never click links from DMs, emails, or ads
  ☐ Keep software and firmware updated
Security is not a one-time setup — it's a habit. Review this checklist monthly. Revoke old approvals quarterly. Update passwords when breaches are announced.
