Password for
Binance
Binance requires a minimum of 8 characters and accepts uppercase, lowercase, numbers and symbols, but an 8-character password is far too weak to guard an account that can hold and trade cryptocurrency — short strings are cracked offline in moments once a hash leaks. Binance caps passwords at 20 characters, so the strongest practical choice is to use that full allowance: a 20-character random string spanning the complete character set, delivering roughly 131.1 bits of entropy. At the cap, the space of possible passwords is astronomically large — far longer than the universe has existed to exhaust by brute force. Generate one below: it is created inside your browser using the Web Crypto API and is never sent to a server or stored anywhere. Combine it with app-based two-factor authentication — an authenticator app or hardware key rather than SMS — so a stolen password alone cannot reach your funds.

Binance password rules
Crypto account breaches are irreversible — funds cannot be recovered. Use a password you've never used anywhere else, and always enable 2FA.
Because Binance limits passwords to 20 characters, the recommended length sits exactly at the maximum the platform allows — so you lose nothing by using every character. At the 8-character minimum, a full-keyset password yields about 52.4 bits of entropy, below the 80-bit level NIST SP 800-63B recommends for high-value accounts. Filling the 20-character cap raises that to roughly 131.1 bits. The jump is not incremental but astronomical: each additional random character multiplies the number of candidates an attacker must test. A 52.4-bit password is within reach of GPU-driven cracking of leaked hashes; 131.1 bits is computationally unreachable, comfortably clearing the NIST threshold for an account holding tradeable assets.
Why Binance accounts are targeted
Binance accounts attract attackers because crypto transactions cannot be undone: funds moved to an attacker's wallet are gone, with no reversal and little hope of recovery. That irreversibility makes a working login directly cashable, so criminals invest in credential stuffing — reusing passwords exposed in unrelated breaches — and in SIM-swap attacks that hijack a victim's phone number to intercept SMS codes and seize the account. Across exchange compromises, phishing and SIM-swapping are the dominant, well-documented vectors rather than platform-side breaches. A long, unique password held only in your browser, backed by app-based or hardware 2FA, closes off the two cheapest and most common routes attackers take.
