Global Out-of-Band (OOB) Authentication Market to Reach USD 7.5 Billion by 2033, Accelerated by Increasing Number of Security Breaches and Cyber Threats

As per the latest report by IMARC Group, titled "Out-of-Band (OOB) Authentication Market Report by Component (Solution, Services), Authentication Channel (SMS, Email, Push Notification, Voice, Token-based, and Others), Deployment Mode (On-premises, Cloud-based), Enterprise Size (Large Enterprises, Small and Medium-sized Enterprises), Industry Vertical (BFSI, IT and Telecom, Government and Defense, Retail, Healthcare, Media and Entertainment, and Others), and Region 2025-2033,” the global out-of-band (OOB) authentication market size reached USD 1.5 Billion in 2024. Out-of-band (OOB) authentication is a method that verifies a user's identity through an alternative channel separate from the primary communication channel, providing an extra layer of security. This authentication technique utilizes two separate channels, typically a mobile device or email, to validate the user's identity. OOB authentication offers numerous benefits, as it significantly reduces the risk of unauthorized access and identity theft as it requires an additional verification step. It is a highly user-friendly method that helps mitigate the risk of unauthorized access or fraudulent activities. It also eliminates the need for users to remember complex passwords or carry physical tokens, as they can receive the authentication codes on their mobile devices or email accounts. Furthermore, the authentication can be implemented across various platforms and devices, making it a versatile solution for organizations operating in multi-device environments. Currently, the different types of out-of-band authentication include SMS-based authentication and voice-based authentication.

Global Out-of-Band (OOB) Authentication Market Trends:

The global out-of-band (OOB) authentication market is primarily boosted by a multitude of factors, including the increasing number of security breaches and cyber threats. This is further accelerated by the surging product application across industries to protect sensitive data and prevent unauthorized access. OOB authentication provides an additional layer of security by leveraging separate communication channels, such as SMS, email, or phone calls, to verify user identity, reducing the risk of fraudulent activities. Moreover, the rapid growth of digital transformation initiatives and the escalating adoption of mobile and cloud-based technologies are driving the market growth. Furthermore, the stringent government regulations and the surging adoption of online banking, e-commerce, and digital payment platforms are fueling the market growth. Besides this, the growing awareness of the limitations of traditional password-based authentication methods and the rapid adoption of bring-your-own-device (BYOD) policies are propelling the market growth. Furthermore, the rising need for secure access to corporate networks and sensitive data and the burgeoning adoption of the Internet of Things (IoT) devices are augmenting the market growth. Other drivers include the escalating need for multi-factor authentication solutions, the integration of biometric authentication with OOB methods, the demand for strong customer authentication in the banking and financial sector, the need for secure access to critical infrastructure and systems, and the advancements in OOB authentication technologies, are influencing the market growth. Looking forward, the market value is projected to reach USD 7.5 Billion by 2033, expanding at a CAGR of 18.7% during 2025-2033.
