Password for
Gemini
Gemini requires a minimum of 8 characters and accepts uppercase, lowercase, numbers and symbols, but for an exchange account holding cryptocurrency an 8-character password is far too weak — short strings collapse quickly under offline cracking and credential-stuffing once a hash is exposed. The practical recommendation in 2026 is a 20-character random string spanning the full character set, which delivers roughly 131.1 bits of entropy. At that length the number of possible combinations is astronomically large — vastly longer than the universe has existed to brute-force — placing the password beyond any realistic attack. Generate one below: it is created inside your browser using the Web Crypto API and is never transmitted to a server or stored anywhere. Combine it with app-based two-factor authentication — an authenticator app or hardware security key rather than SMS — so that a leaked password alone can never unlock your funds.

Gemini 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 Gemini's minimum and a sound password is wide. An 8-character password built from the full keyset carries about 52.4 bits of entropy, below the 80-bit threshold NIST SP 800-63B sets for high-value accounts. A 20-character random string lifts that to roughly 131.1 bits — an astronomical rather than incremental gain, since every added random character multiplies the candidate space. Whereas 52.4 bits is tractable for GPU clusters working against leaked hashes, 131.1 bits is computationally unreachable by any hardware on the horizon. For an account custodying crypto, the NIST 80-bit guideline is the minimum to satisfy, and 131.1 bits exceeds it by an enormous margin.
Why Gemini accounts are targeted
Gemini accounts are attacked because crypto transactions are irreversible: funds moved to an attacker's wallet cannot be recalled, reversed, or charged back. That finality makes a valid login immediately profitable and worth real attacker effort. The dominant documented routes are phishing and SIM-swapping — seizing a victim's phone number to intercept SMS verification codes — alongside credential stuffing that replays passwords leaked in unrelated breaches. These vectors target the user, not the exchange's infrastructure, which is precisely why account-level defences matter most. A long, unique password generated locally in your browser, paired with app-based or hardware 2FA, removes the two cheapest paths attackers depend on to reach your funds.
