Password for
Coinbase
Coinbase requires a minimum of 8 characters and accepts uppercase, lowercase, numbers and symbols, but for an account that can hold and move cryptocurrency, an 8-character password is far too weak — short strings fall quickly to offline cracking and credential-stuffing. The practical recommendation in 2026 is a 20-character random string drawing on the full character set, which delivers roughly 131.1 bits of entropy. At that strength the number of possible combinations is astronomically large — vastly longer than the universe has existed to brute-force — making the password effectively impossible to guess or crack. Generate one below: it is created inside your browser using the Web Crypto API and is never transmitted to a server or stored anywhere. Pair the password with app-based two-factor authentication (an authenticator app or hardware security key rather than SMS), so that even a leaked password alone cannot grant access to your funds.

Coinbase password rules
Crypto account breaches are irreversible — funds cannot be recovered. Use a password you've never used anywhere else, and always enable 2FA.
The gap between Coinbase's floor and a sound password is enormous. An 8-character password built from the full keyset carries about 52.4 bits of entropy, well below the 80-bit threshold that NIST SP 800-63B treats as appropriate for high-value accounts. A 20-character random string pushes that to roughly 131.1 bits — not a marginal improvement but an astronomical one, since each added character multiplies the search space. Where 52.4 bits is tractable for modern GPU clusters fed by leaked hashes, 131.1 bits is computationally unreachable by any foreseeable hardware. For an account custodying crypto, clearing the NIST 80-bit bar is the minimum bar to clear, and 131.1 bits clears it by a wide margin.
Why Coinbase accounts are targeted
Crypto exchange accounts are prized targets because transactions are irreversible: once an attacker drains funds to a wallet they control, there is no chargeback, no bank reversal, and rarely any recovery. That finality makes Coinbase logins worth the effort of credential stuffing — replaying passwords leaked from other breaches — and of SIM-swap attacks, where a criminal hijacks your phone number to intercept SMS codes and reset access. The dominant documented routes to compromised exchange accounts are phishing and SIM-swapping rather than exchange-side failures, which is exactly why a long, unique password plus app-based or hardware 2FA matters: it removes the two cheapest paths attackers rely on.
