Token2 TOTPRadius Virtual appliance
download purchase integration guides
Token2 TOTPRadius provides the RADIUS RFC-2865 for TOTP RFC-6238 based authentication. With TOTPRadius you can integrate a large variety of third-party products and systems with multi-factor authentication. A number of enterprise products and services like VPNs, Citrix XenApp/XenDesktop, VMWare View and many others provide support for RADIUS servers to validate the second factor of user authentications. Additionally, TOTPRadius appliance is providing RESTful API for second-factor authentication and enrolment (including self-service enrolment where possible). This allows implementing a fully on-premises secure and user-friendly two-factor authentication supporting RADIUS and LDAP protocols together with HTTP API with one appliance. TOTPRadius supports OTP-only authentication based on RFC-6238 algorithm (TOTP: Time-Based One-Time Password Algorithm), Local password + OTP combined authentication as well as LDAP+OTP combined authentication. It provides a web-based administration panel and an HTTPS REST-based API service designed to enable users' self-enrollment.
VPN Portal is a subcomponent of TOTPRadius appliance and is required to implement several features, such as LDAP-based self-service enrollment, FIDO2/Passwordless or Azure AD Oauth2/SSO VPN access. To ensure the security of the VPN Portal is at the highest level, we have contracted an independent security company, SySS GmbH , which has conducted the penetration testing and produced a security certificate available below. The TOTPRadius VPN Portal component is currently labeled as "Certified Website - Approved Security" by SySS Gmbh.
Self-enrollment using RESTFul API
The main advantage of TOTPRadius is the RESTFul API that allows users to self-enrol with their software tokens such as Google Authenticator and Token2 Mobile OTP. An example of such an integration is a self-enrollment mechanism with Citrix Netscaler/StoreFront. The integration can be done by installing our Storefront integration package and adding a new RADIUS authentication server on the Netscaler. It usually takes not more than five minutes to implement. Refer to Citrix integration manual for more details.
Self-enrollment using LDAP Enroll web interfaceYou can configure TOTPRadius to allow users to log in without second factor (e.g. using AD password only) for the first time and then navigate to TOTPRadius LDAP Enroll web interface (accessible only within your local network or VPN), where they can enrol the second factor independently. Administrators can also allow modifying (reenrolling) via LDAP Enroll web interface.
The principle behind LDAP Proxy mode is that users will provide their AD or LDAP password together with the one-time passwords in the password field. TOTPRadius will then parse the password, split it into two parts and authenticate the OTP and if correct will send the AD/LDAP password part further to the AD/LDAP server configured. The order of authentication is exactly as stated above, OTP is checked first and AD after OTP is confirmed correct; this is done in order to prevent account lockouts during brute force attacks. Enabling LDAP Proxy on your TOTPRadius appliance allows implementing two-factor authentication for systems that do not natively support it, such as Cisco Meraki VPN, Cisco WLC and many others
No LDAP? Use Azure AD Proxy
We are discovering more and more organizations moving to full cloud Azure AD implementation while keeping some services, such as VPN, on-premises. As the LDAP interface of Azure AD is not accessible directly, it was not possible to configure TOTPRadius to use Azure AD as its authentication source.
High availability and hardware token managementStarting from version 0.2.2 TOTPRadius appliances can be configured in high availability mode. Appliances in slave mode will only contain a read-only database will periodically synchronize with their master appliance via HTTPS REST API.
Starting from version 0.2.4, TOTPRadius has a built-in management interface for hardware tokens. The hardware management tool allows adding and importing hardware token data, verify and adjust time drift using the virtual TOTP emulator and assign the hardware token to any user with a couple of clicks.
Download & install
TOTPRadius is deployed as a software-based virtual appliance that runs on two hypervisors: VMWare ESXi and Microsoft Hyper-V. Upon request, virtual appliances for other hypervisors can be provided. It is free to use with up to 5 users. You need to obtain a license to increase the number of allowed users. You can download the appliance here

Azure AD Authentication methods policy migration
In an effort to enhance security and streamline administration, Microsoft introduced the Authentication methods policy for Azure AD. This policy allows administrators to manage the MFA and SSPR settings from a single location, simplifying the overall user experience. However, it's important to note that the migration process has a limitation when it comes to hardware OATH tokens.
