Dynamic MFA: The Key to NYDFS Cybersecurity Compliance

Cybersecurity in financial services has never been more critical. With rising cyberattacks, data breaches, fraud, and identity theft, regulators are tightening the screws on financial institutions that fail to protect their customers. The New York State Department of Financial Services (NYDFS) cybersecurity regulation (23 NYCRR 500) has set a clear expectation: financial firms must implement strong multi-factor authentication (MFA) into their cybersecurity programs and secure digital identities to safeguard customer data, transactions, and sensitive systems.

As we move into 2025, compliance is no longer optional. Failure to meet MFA authentication standards and protect data privacy could lead to regulatory fines, reputational damage, and increased cybersecurity risks. However, compliance isn’t just about avoiding penalties—it’s about securing digital banking, fintech, embedded finance, and open banking ecosystems against current and future cybersecurity threats.

For many financial institutions, the biggest challenge is finding the right balance between security, compliance, and customer experience. Traditional MFA solutions, such as SMS-based one-time passwords (OTPs), are now considered weak authentication methods, vulnerable to unauthorized access via phishing, SIM-swapping, and credential-stuffing attacks. That means organizations must move toward more secure and frictionless authentication approaches, including passkeys, FIDO2 authentication, WebAuthn, security keys, and passwordless authentication, to enhance network security.

NYDFS 23 NYCRR 500 is one of the most stringent cybersecurity regulations for financial services. It applies to banks, insurance companies, mortgage lenders, investment firms, and other financial institutions operating in New York. The regulation mandates strong security controls, including multi-factor authentication (MFA) or equivalent measures to protect sensitive data.

By 2025, regulators are expected to ramp up enforcement of MFA authentication requirements. Organizations must ensure that any access to nonpublic information (NPI) and critical systems is secured with strong, phishing-resistant authentication methods. Institutions must also prove compliance through robust identity verification, Know Your Customer (KYC) measures, password management, and fraud prevention technologies.

For financial services, the consequences of non-compliance are steep. NYDFS has already issued fines in the millions for cybersecurity events and other failures, with penalties ranging from regulatory enforcement actions to reputational damage that erodes customer trust. The financial services industry is a prime target for cybercriminals, and weak authentication practices make it even easier for attackers to exploit stolen credentials.

Many financial institutions already use MFA authentication, but not all MFA solutions meet the high-security standards required by NYDFS. The most common method—SMS-based one-time passwords (OTPs)—are now widely considered inadequate.

Cybercriminals can easily intercept SMS OTPs through SIM-swapping attacks, phishing scams, and man-in-the-middle attacks. Once they gain access to a victim’s authentication code, they can bypass security controls, take over accounts, and conduct fraudulent transactions. In the financial services industry, where digital banking, BNPL, and embedded finance transactions happen at lightning speed, this creates a serious security risk that could severely impact business operations and business continuity.

To meet compliance requirements and strengthen data security, financial institutions, and other regulated entities must move beyond outdated MFA methods and embrace passwordless authentication, passkeys, WebAuthn, and FIDO2 authentication. These technologies provide phishing-resistant authentication and eliminate reliance on passwords and weak second factors like SMS OTPs.

Financial organizations need a future-proof authentication strategy—one that satisfies NYDFS regulations while also improving customer experience. Ping Identity delivers dynamic authentication solutions that enable financial services firms to implement strong digital identity protections, eliminate weak authentication methods, and prevent fraud.

1. Phishing-Resistant MFA Authentication That Meets NYDFS Standards

Ping Identity's comprehensive MFA solutions help financial institutions achieve compliance with NYDFS while improving security. Instead of relying on weak second factors like SMS OTPs, through full coverage and support for:

• Passkeys and FIDO2 authentication, which eliminate passwords and replace them with cryptographic authentication mechanisms that are immune to phishing.

• WebAuthn and security keys, which provide stronger identity verification and secure access to financial applications.

• Magic links and OIDC-based authentication, which reduce friction while ensuring users are securely verified before accessing accounts.

These authentication methods support vulnerability management, protecting customer digital identities, preventing credential theft, and helping financial institutions meet NYDFS cybersecurity mandates with confidence.

2. Secure Digital Banking, Open Banking, and Embedded Finance

As financial services continue to evolve, security must extend beyond traditional banking platforms. Ping Identity enables financial institutions to secure digital banking, fintech, BNPL, decentralized finance (DeFi), and embedded finance ecosystems with strong authentication and identity verification solutions.

The Ping Identity Platform helps financial organizations implement:

• OpenID Connect (OIDC) and tokenization, ensuring transactions and sensitive information are protected against fraud.

• Adaptive authentication, which uses real-time risk analysis to determine whether a login attempt is suspicious and requires additional verification.

• Seamless authentication for fintech and embedded insurance, enabling secure and frictionless user experiences across multiple financial applications, including third-party service providers.

3. Strengthened KYC Compliance and Fraud Prevention

Financial institutions are required to comply with Know Your Customer (KYC) and Anti-Money Laundering (AML) regulations, ensuring only verified customers gain access to financial services. Ping Identity enhances KYC compliance by integrating advanced identity verification technologies that help organizations verify users without unnecessary friction.

The Ping Identity Platform helps financial organizations:

• Implement verified trust solutions using biometric authentication, government-issued IDs, and decentralized identity verification.

• Strengthen fraud prevention with risk-based authentication and real-time monitoring of suspicious login attempts.

• Improve password management and identity federation, ensuring secure and seamless access and application security.

By adopting these solutions, financial institutions can protect against fraudulent activity while also ensuring compliance with both NYDFS and broader financial cybersecurity mandates.

Failing to comply with NYDFS cybersecurity regulations isn’t just about potential fines and remediation costs—it’s about staying ahead of cyber threats that continue to target the financial sector. A weak authentication and risk management strategy increases the risk of:

• Account takeovers and financial fraud, leading to direct financial losses.

• Regulatory penalties, with NYDFS issuing enforcement actions against non-compliant firms.

• Loss of customer trust, as security breaches erode confidence in a financial institution’s ability to protect digital identities.

For chief information security officers (CISOs) at financial institutions, traditional MFA is no longer enough. The best way to stay compliant—and protect both the institution and its customers—is to adopt phishing-resistant authentication, decentralized identity verification, and strong digital identity protections.

The financial industry is at a turning point. With NYDFS and other governing bodies ramping up enforcement of cybersecurity mandates and stringent financial services laws, financial institutions must prioritize strong MFA authentication and digital identity protections. Organizations that fail to do so will not only risk compliance violations but also open themselves up to devastating cyberattacks.

The Ping Identity Platform helps financial organizations firms:

• Achieve NYDFS compliance with strong MFA, passwordless authentication, and adaptive access privileges.

• Protect customers’ digital identities with phishing-resistant security measures.

• Secure digital banking, fintech, open banking, and embedded finance transactions and information systems.

• Prevent fraud and strengthen KYC compliance with verified trust solutions and secure data retention.

By adopting a stronger cybersecurity framework, financial services companies don’t just meet regulatory standards—they actively build customer trust, fostering long-term relationships based on security and confidence across every digital moment.
