I am looking for a way to generate Oracle Mobile Authenticator OTP on Linux. Oracle Mobile Authenticator is based on Google Authenticator. So I figured I should be able to use JAuth (Java based Google Authenticator Token generator app). But it seems like I am not able to initialize JAuth using the Secret generated by the Oracle Access Manager for the OTP.
Google Authenticator complies to HOTP/TOTP (RFC 4226 6328) Take a look at oathtool, which is a command line implementation of HOTP/TOTP.
