How Passwords Get Hacked
๐ 7 min read
Quick Answer
Most accounts are not "hacked" by genius coders breaking encryption โ they fall to a handful of boring, predictable tricks. The good news: understanding those tricks reveals exactly how to defend yourself, and it is easier than you think.
๐ก Think of it asโฆ
Burglars rarely pick locks โ they try doors people left unlocked, copy keys that leaked, or trick you into opening up. Password attacks work the same way: they exploit reuse and human error, not unbreakable math.
Breaches and password reuse
When one site is breached, attackers get email/password pairs and immediately try them everywhere else ("credential stuffing"). If you reuse a password, one leak can unlock your email, exchange, and bank. Reuse is the single biggest risk.
Phishing and social engineering
Often the easiest route is simply asking: a fake login page or "support" message tricks you into typing your password. No cracking required โ you handed it over. This is how most crypto thefts of individuals begin.
Brute force and weak passwords
Short, common, or predictable passwords can be guessed by software trying billions of combinations. Length and randomness defeat this โ a long passphrase is exponentially harder than a short complex one.
The defense
Use a password manager to create a unique, long, random password for every site; turn on app-based 2FA; and treat unsolicited login links as hostile. These three habits stop the overwhelming majority of attacks.
๐ Key takeaway
Passwords mostly fall to reuse (after breaches), phishing, and weak choices โ not broken encryption. A password manager (unique passwords everywhere) plus app-based 2FA defeats almost all of it.
Why this matters for you
Crypto raises the stakes: a reused password plus a breached exchange can mean stolen funds with no recourse. Adopting a password manager and 2FA โ and self-custody for serious holdings โ is the practical defense for anyone holding crypto in Asia.
Frequently asked questions
Are password managers safe?โผ
Reputable password managers are far safer than reusing passwords or storing them in a browser/notes. They encrypt your vault behind one strong master password โ which you should pair with 2FA.
What makes a strong password?โผ
Length and randomness beat complexity tricks. A long, random passphrase (or a manager-generated string) unique to each site is ideal. Never reuse passwords across important accounts.
How does this affect my crypto?โผ
Exchange and email accounts are gateways to your funds. Unique passwords + 2FA protect them; self-custody removes the exchange as a single point of failure entirely.
