To enable or disable software OTP tokens for a specific application:
LoginTC software OTPs require the following LoginTC App versions:
If your device has an older version of the LoginTC App you may upgrade to the newest version from your platform’s app store.
When authenticating, a user enters their username normally. In the password field, they should should enter their password followed immediately by a comma and the One-Time Password (OTP) displayed on the LoginTC app. The OTP is valid for 30 seconds. An indicator beside the OTP informs the user how much time is left.
Regular input (without OTP):
username: john.doe password: johnPassword
Input with OTP:
username: john.doe password: johnPassword,253340
If the OTP is valid, the user will be authenticated without a request being sent to their 2nd factor device. If the OTP is invalid the user’s request will be denied.
There must not be any spaces between the password, the comma, and the OTP
Using OTPs with Challenge Authentication Mode (LoginTC RADIUS Connector)
The software OTPs work great with the Challenge Authentication Mode if you are using the LoginTC RADIUS Connector and if your RADIUS clients support it. When using the Challenge Authentication Mode, the user will be prompted to enter an OTP or press 1 to proceed with the standard LoginTC Push authentication.
If your users are having difficulty authenticating with OTPs, check the Logs page in the LoginTC RADIUS Connector web interface:
