TOTP ME

Java ME TOTP (RFC 6238) authenticator. It can be used as a token generator for:
Google’s two phase authentication
LinOTP authentication
other authentication servers which support TOTP

Features:
multiple profiles/accounts supported
configurable parameters
secret key
profile name
digest algorithm: SHA-1 (default), SHA-256, SHA-512
number of token digits (default is 6)
time step (default is 30)
time correction (default is 0) - advanced feature, the value (may be negative) is added to the device’s system time during computing a token value
input validation
key generator with Base32 and HEX output

How to use it
You either have already a secret key, then fill it as Base32 encoded String after the start (Options form is displayed if no key is set already). Or you can generate the secret key directly by the application
and then fill it as a shared secret in the authentication server.

Generate new secret key
choose your preferred digest algorithm in the Options screen (the default is SHA-1)
choose Key generator from the menu - it will switch you to screen for generating the new key
use New key command to generate a new key, you can use it more times if you are not satisfied with the generated value
fill the HEX value in you authentication server configuration
press OK command and you will be switched back to the Options screen; confirm your configuration and press OK command again
if no problem occurs, you are switched to the main application screen, where the Token value is already present
you can synchronize the authentication server with your token now
