Enhancing Legacy Applications with Single Sign-On (SSO) and Multi-Factor Authentication (MFA)

There existed a period where the amalgamation of usernames and passwords was deemed sufficient to safeguard software applications against unauthorized access. However, it is evident that the realm of security is in a state of perpetual evolution, compelling enterprises to stay abreast with avant-garde solutions. For businesses utilizing antiquated systems, the risks are significantly more perilous compared to individual users. Leveraging such systems can perilously expose an organization’s cybersecurity. Applications structured for older platforms or those not web-enabled are termed as legacy applications. Despite functioning as intended, these necessitate meticulous security measures to guarantee enduring safety.

Legacy applications are prevalent across various business domains due to their specific utility. Particularly in sectors like healthcare, finance, government, and manufacturing, technologies are devised for designated purposes and don’t necessitate upgrades often. Examples include specialized and isolated equipment like MRI machines, and isolated databases and software in local government offices, which may not have received updates due to lack of perceived necessity and the resources required for such upgrades. However, software based on platforms no longer receiving security updates is vulnerable.

The executive order released by President Biden in May 2021 obligated federal agencies to revamp their cybersecurity defenses, enforcing the adoption of genuine MFA technologies. This mandate isn’t exclusive to government entities; companies within the federal government supply chain, and their vendors, are also required to adhere. Non-compliance post the deadline implies severe penalties.

However, integrating SSO or MFA technology with legacy applications, not originally designed to accommodate advanced MFA, poses significant challenges. Many are faced with the daunting option of rewriting the application, a strenuous and costly endeavor given the constant evolution of MFA technologies. Another substantial challenge arises when there is no access to the source code of commercial legacy applications, making modifications or integrations highly complex and limiting. This lack of access to foundational code layers obstructs the direct implementation of enhanced security protocols, necessitating innovative solutions to circumvent such limitations. CodeB emerges as such an innovative solution, allowing instant integration of advanced security measures including passwordless authentication options, without access to the source code or the need for extensive modifications to the existing system.

Fortunately, CodeB enables organizations to introduce SSO, MFA, or Passwordless Authentication to legacy applications without altering or rewriting them. CodeB’s software-agnostic solution can be implemented instantly, ensuring continuous compliance with the executive order and access to the latest MFA, SSO, or Passwordless Authentication solutions. This empowers organizations to fortify their data against cyber threats and provide assurance to their clients regarding information security, all while avoiding the incessant cycle of application updates to align with emerging technologies.


For organizations grappling with outdated systems, enhancing legacy applications with advanced security measures like Single Sign-On, Multi-Factor Authentication, and Passwordless Authentication is crucial. Leveraging innovative solutions like CodeB enables instantaneous implementation of these advanced features without the need for extensive modifications or developments, ensuring optimal compliance and data security in the ever-evolving technological landscape.
