SafeNet eToken 5100 is a portable two-factor authentication USB token with advanced smart card technology. It utilizes certificate-based technology to generate and store credentials, such as private keys, passwords, and digital certificates inside the protected environment of the smart card chip. 

To authenticate, users must supply both their personal SafeNet authenticator and password, providing a critical second level of security beyond simple passwords to protect valuable digital business resources.

Future Proofed and Scalable with Centralized Management Control

SafeNet eToken 5100 integrates seamlessly with third party applications through SafeNet Authentication development tools, supports SafeNet PKI and password management applications and software development tools, and allows customization of applications and extension of functionality through on-board Java applets. It is also supported by SafeNet Authentication Manager, which reduces IT overhead by streamlining all authentication operations including deployment, provisioning, enrollment and ongoing maintenance, as well as offering support for lost tokens.
