Authentication Methods

Software Authenticator

3Si software authenticator solutions combines the security of proven multi-factor strong authentication with the convenience, simplicity, and ease of use of OTPs generated on personal mobile devices or PCs. By turning a mobile device into a multi-factor authentication device, organisations save significantly on hardware and deployment costs, while users benefit by not having to carry an additional hardware token around with them.

Compatible with the broadest range of devices and mobile clients, providing powerful identity protection and convenient access control for remote access systems, such as VPNs, Citrix applications, Cloud applications, Outlook Web Access, and Web portals. It also offers strong authentication for secure local network access.

Automated provisioning and activation with zero wait, web-based cloud self-service portals offer 24x7 support for users, further reducing helpdesk calls and overall TCO which in turn increases user satisfaction. Policy-based activation determines the token configuration hence significantly reducing deployment complexities, IT administration overhead, and costs when implementing strong authentication for thousands of users.

Optimized Security with sophisticated security capabilities, including standards-based activation and dynamic seeding, allow organizations to optimize the balance between ease-of-use and TCO without compromising on security.
