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.

Security note

Crypto account breaches are irreversible — funds cannot be recovered. Use a password you've never used anywhere else, and always enable 2FA.

The maths, specific to Binance

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.
