Echidna is agnostic to the authentication mechanism and provides wide support for a range of standard, proprietary and brokered methods, for example:
Salt Mobile tokens that are standalone mobile apps (or embedded SDK) that is supported across a range of mobile devices and platforms, including Android and iOS, with limited support on Windows Phone, Blackberry and Symbia
Hardware security tokens that are compliant to the OATH HOTP, TOTP or OCRA standards
Proprietary soft security tokens running as an App installed on mobile devices
“Second Channel” one time passwords delivered to a user via SMS or email.
Echidna can also proxy authentication requests to third party servers to support legacy or proprietary tokens such as RSA SecurID and Vasco tokens.
