Account Security and Two-Factor Authentication

Most beginners lose crypto not through exotic hacks but through a hijacked exchange or email account. The good news: a few basic habits block the overwhelming majority of these attacks. This is about securing the accounts around your crypto, which complements protecting your seed phrase.

Strong, unique passwords

Reusing one password everywhere means a single leak elsewhere can open your exchange account. Use a long, unique password for every account, and let a reputable password manager generate and remember them. This one change closes off a huge category of attacks.

Turn on two-factor authentication (2FA)

Two-factor authentication adds a second step beyond your password — a code that changes constantly — so a stolen password alone isn't enough. Always turn it on for your exchange and the email tied to it. But not all 2FA is equal:

• Authenticator app (good). Apps like an authenticator generate codes on your device. Strongly preferred.
• Hardware security key (best). A physical key is the most phishing-resistant option.
• SMS text codes (weak). Better than nothing, but vulnerable to "SIM swapping," where an attacker hijacks your phone number. Avoid SMS for crypto where you can.

Protect the email account too

Your email is the master key to everything — most password resets go through it. Give it its own strong password and its own strong 2FA. An attacker who owns your email can often reset their way into your other accounts.

Beware the human attacks

Technical defenses don't help if you hand the keys over. Real support will never ask for your password, 2FA codes, or seed phraseA list of 12–24 words that backs up a wallet. Whoever has it can restore — and drain — the wallet.. Anyone who does is a scammer. Type exchange addresses yourself or use a bookmark rather than clicking links in emails or messages.

Key takeaways

• Most beginner losses come from account takeovers, which basic habits prevent.
• Use a long, unique password for every account, managed by a password manager.
• Turn on two-factor authentication — prefer an authenticator app or hardware key over SMS.
• Secure the email account tied to your exchange just as strongly; it's the master key.
• No legitimate support ever asks for your password, 2FA codes, or seed phrase.
