Why secure login matters
Access to a crypto exchange account is access to value. Unlike many online services, once crypto leaves an account it is difficult or impossible to reverse. That’s why each login should be treated as a high-value operation: small mistakes — reused passwords, missed MFA prompts, or a single phishing click — can lead to permanent loss.
Before you log in: prepare your environment
Always verify that you are on the official site by checking the URL (use bookmarks or typed addresses rather than links in emails). Use up-to-date device software and a reputable browser. Avoid logging in on public computers or open public Wi-Fi networks. If you must use a public network, enable a trusted VPN, and treat the session as untrusted until you reach a secure network.
Create a strong, unique password
Choose a password that’s long (12+ characters) and a mix of words, punctuation and numbers. Don’t reuse passwords across sites. The easiest way to manage strong unique passwords is a well-reviewed password manager — it both creates random credentials and fills them into forms securely so you don’t copy/paste sensitive text.
Enable Multi-Factor Authentication (MFA)
MFA is your second line of defense. Prefer time-based one-time password (TOTP) apps (e.g., Authenticator apps) or, even better, hardware security keys (FIDO2 / YubiKey) when supported. Avoid SMS-based MFA where possible: SMS can be intercepted or SIM-swapped by attackers.
Recognize phishing and social engineering
Phishing sites and messages are the most common vectors for account takeovers. Red flags include urgent language, unexpected attachments, typos in the domain name, or email addresses that don’t match the official support domain. When in doubt, do not click a link — open a new browser tab and navigate to the site directly via bookmark or search.
Proof checks you can do in seconds
- Verify the URL: ensure the domain exactly matches the official domain (no extra characters, no subdomain tricks).
- Check TLS/SSL certificate: click the padlock next to the address bar and confirm the certificate is valid.
- Look for official channels: support pages, status pages, or official social profiles can confirm maintenance windows or outages before you panic.
Session hygiene and device management
Sign out when you finish tasks on shared devices. Periodically review connected devices and active sessions from your account settings and revoke unfamiliar ones. Use device-based security features: enable device passcodes, biometrics, or platform encryption. For particularly sensitive accounts, consider a dedicated device solely for financial operations.
Keeping backups and account recovery secure
Recovery phrases and backup codes are the keys to restore access — treat them like gold. Store backups offline in secure locations: a hardware vault, a safe deposit box, or a physically-secure home safe. Avoid storing recovery phrases in cloud notes, email, or unprotected photos. If your exchange provides downloadable recovery codes for MFA, keep them encrypted and offline.
When you see suspicious activity
If you notice unfamiliar deposits, withdrawals, or login attempts, immediately revoke active sessions, change your password to a new random value, and revoke API keys. Contact the platform’s official support channel (navigate directly from the official site — don’t use links from unknown emails). Often exchanges have emergency procedures and can freeze withdrawals temporarily while an investigation proceeds.
Best practices summary (quick checklist)
- Use a password manager and a unique, long password for each service.
- Enable MFA — prefer TOTP apps or hardware security keys.
- Verify website URLs and TLS certificates before logging in.
- Keep device OS and browser up to date; avoid public Wi-Fi without VPN.
- Store recovery phrases offline and treat them as sensitive valuables.
- Regularly review active sessions, API keys, and connected devices.
- If compromised, immediately revoke access, change passwords, and contact support.
