Kraken Crypto Security
Kraken crypto security represents the industry's most rigorous approach to safeguarding digital assets and personal data. By combining military-grade encryption, extensive physical safeguards, and continuous penetration testing, we ensure your portfolio remains protected against emerging cyber threats. Our security philosophy is built on the principle of "Defense in Depth," where multiple layers of protection ensure that even if one layer is compromised, your assets remain secure. Safeguard your holdings further with our non-custodial wallet solutions.
Our comprehensive asset protection framework is designed from the ground up to eliminate single points of failure. Whether you are an individual trader managing your Kraken account or a large institutional investor, you can trade with confidence knowing that our dedicated global security team monitors our infrastructure 24/7/365. We maintain full regulatory compliance and continuously invest in the latest security technologies to stay ahead of malicious actors.
Secure Your Account
What Is Air-Gapped Cold Storage?
Air-gapped cold storage is an offline asset protection methodology where private keys are stored on physical devices that never connect to the internet or any network. At Kraken, we maintain 95% of all client deposits in geographically distributed, heavily guarded cold storage facilities around the world. This isolation guarantees that even in the highly unlikely event of a sophisticated online breach, the vast majority of user funds remain completely inaccessible to malicious actors. Our cold storage system is the gold standard for asset protection, providing a level of security that online "hot" wallets simply cannot match.
Our cold storage vaults require multiple authorized signatures from senior executives to move funds, ensuring no single individual can compromise the system. The remaining 5% of assets are kept in highly secure, multi-signature hot wallets to provide the necessary liquidity for rapid, real-time trading and seamless withdrawals. By maintaining this strict ratio, we balance unparalleled crypto security with the high-performance trading experience our users expect. Every withdrawal from cold storage is a manually reviewed and verified process, adding an extra layer of human oversight to our cryptographic protections.
The 95% Guarantee
Our commitment to offline storage is the cornerstone of our defense-in-depth strategy. We continuously audit our reserves to ensure the 95% threshold is rigorously maintained across all supported blockchains. This mathematical certainty provides peace of mind that your digital wealth is backed 1:1 and physically shielded from the digital battlefield. We take this guarantee seriously, and our internal systems are designed to automatically trigger alerts if the ratio of assets in cold storage falls below our strict thresholds, allowing us to take immediate action to rebalance and maintain our security posture.
Advanced Client-Side Crypto Security
Client-side crypto security encompasses the proactive tools and settings we provide to help users lock down their individual accounts against unauthorized access. We empower you with the same professional-grade tools used by our internal security teams.
Hardware Key 2FA (YubiKey)
Hardware-based Two-Factor Authentication (2FA) is a physical security protocol that requires a dedicated USB or NFC device to approve account logins and withdrawals. Kraken strongly recommends YubiKey devices, which use FIDO U2F standards to completely neutralize phishing and SIM-swapping attacks. By requiring a physical touch to authenticate, hardware keys ensure that an attacker cannot access your account even if they have stolen your password and email credentials. This is the most robust form of 2FA available, providing nearly perfect protection against remote account takeovers. We believe that hardware keys should be the standard for anyone serious about their digital asset security.
Withdrawal Allowlisting
Withdrawal allowlisting is an account restriction feature that limits crypto transfers solely to pre-approved, verified external wallet addresses. This prevents unauthorized fund movements even if an account is compromised. By setting a mandatory cooling-off period for new addresses, we provide an additional layer of temporal defense against malicious withdrawal attempts. This means that if an attacker were to gain access to your login, they would be unable to withdraw funds to their own address without waiting for the allowlist period to expire, giving you ample time to detect the breach and secure your account with the help of our 24/7 support team.
PGP Encrypted Email
Kraken provides the option to receive all automated system communications via PGP-encrypted email. By using Pretty Good Privacy (PGP) protocols, we ensure that sensitive account alerts, confirmation links, and balance notifications can only be read by the intended recipient holding the corresponding private key, effectively eliminating email-based data leaks. In an era where email accounts are frequently targeted by hackers, PGP encryption provides a vital layer of privacy and security, ensuring that your communication with Kraken remains confidential and that no one can intercept or forge official messages from our platform.
Global Settings Lock (GSL)
The Global Settings Lock (GSL) is a powerful account-level freeze that prevents any changes to your security settings or withdrawal addresses while active. When the GSL is engaged, it requires a time-delayed unlock process or a secondary Master Key to disable, providing a final line of defense against account takeovers. This feature is particularly effective against "wrench attacks" or other forms of social engineering, as it introduces a physical time barrier that cannot be bypassed by an attacker, no matter how much access they have to your digital credentials. It is a set-and-forget feature that provides massive peace of mind for long-term holders.
Master Key Protection
Our Master Key system allows users to designate a separate set of credentials for critical account actions, such as resetting passwords or disabling 2FA. This ensures that even if a primary login is compromised, the core security architecture of the account remains impenetrable without the secondary Master Key. This separation of concerns is a fundamental principle of high-security systems. Your Master Key can be stored in a completely different location from your primary credentials (for example, on a dedicated hardware device or a secure physical document), ensuring that no single breach can ever grant an attacker full control over your Kraken account.
Active Session Management
Users can monitor and terminate all active sessions in real-time. Our system provides detailed logs of every login attempt, including IP address, geographic location, and device type. Any suspicious activity can be halted instantly with a single click, forcing a logout across all devices. This level of visibility is crucial for identifying potential threats early. If you see a login from an unrecognized device or location, you can immediately lock your account and begin the recovery process. Our session management tools provide you with the situational awareness needed to act as your own security officer, with the full backing of Kraken's global infrastructure.

To maintain our position at the forefront of crypto security, we operate an extensive bug bounty program. We invite the world's most talented security researchers to identify vulnerabilities in our platform, recompensating them for responsible disclosure.
