AI tools add to this application sprawl—centralized authentication through MCP gateways eliminates this friction while maintaining security.

14. 59% of employees use the same or similar passwords across multiple accounts

Password behavior data confirms the security risk created by authentication friction. Password reuse means a single credential compromise can cascade across systems. SSO eliminates the need for multiple passwords, removing the reuse incentive while improving both security and user experience.

15. 89% of consumers have complaints about keeping track of their passwords

Consumer survey data from Ping Identity reveals widespread password fatigue. This frustration extends to enterprise users accessing internal AI tools. SSO addresses the root cause by reducing credential count while maintaining—or improving—security posture through centralized policy enforcement.

16. 54% of consumers have stopped using an account or service because login was too frustrating

User abandonment research demonstrates the productivity cost of poor authentication experiences. In enterprise contexts, frustrating AI tool access leads to workarounds and shadow IT. SSO removes friction while maintaining governance—employees adopt sanctioned tools when access is seamless.

17. 62% of Americans reuse passwords across accounts

Password reuse research confirms this behavior remains endemic despite security awareness efforts. This behavior pattern makes SSO implementation a security necessity rather than convenience enhancement. OAuth-based authentication eliminates passwords from the equation entirely for connected applications and AI tools.

18. A significant portion of consumers have had accounts compromised due to weak or stolen passwords

Survey data quantifies the real-world impact of password-based authentication failures. This compromise rate underscores why enterprises are moving toward passwordless approaches. OAuth/SSO provides the foundation for passwordless migration while delivering immediate security improvements.

Adoption Driver Statistics

19. 66% of organizations adopt SSO to improve access management

Gartner Peer Community data identifies access management as the top driver for SSO adoption. Centralized access control enables consistent policy enforcement across applications—including AI tools. MintMCP's role-based access control extends this governance to MCP servers with granular tool-level permissions.

20. 56% adopt SSO to solve poor end-user password practices

Enterprise adoption research shows password hygiene concerns drive over half of SSO implementations. Rather than relying on training and policy to improve password behavior, SSO removes the problem by eliminating distributed passwords. This approach proves more effective than attempting to modify entrenched user habits.

21. 55% adopt SSO to reduce IT support ticket requests

Support cost data reveals operational efficiency drives SSO adoption alongside security concerns. Password resets consume significant IT resources—SSO reduces this burden while improving user productivity. For organizations deploying AI tools, reduced support overhead enables IT teams to focus on strategic initiatives.
