SailOTP

SailOTP is a Sailfish Implementation of the Google-Authenticator algorithms, also known as TOPT (timer based) and HOTP (counter based) as described in RFC 6238 and 4226. A growing number of sites uses this algorithm for two-factor-authentication, including Github, Linode and several Google services.

One can add new OTP-entries using the pulley-menu. The type of token can be selected. Title and the shared secret have to be provided. For counter based HOTP-tokens the counter value for the next update of the Token can be set. The default of 1 is the standard value for new HOTP-tokens and should not be changed.

The main view of the app will show a list off all entries and their current One-Time-Tokens. The entries will be regenerated every 30 seconds, the remaining time for the current tokens is shown through a progress bar at the top of the app. HOTP-type tokens are not updated automatically, instead a refresh button is shown on the right of the token to calculate the next value and increment the counter An entry can be edited or deleted by long-pressing on it.

One entry can be stared by tapping the star icon on the left. the stared item will be shown on the ActiveCover. If the Token is timer based, it will be refreshed every 30 seconds. 5 seconds before the token changes it's color will change to red. For counter based tokens a cover action to calculate the next token is shown instead. The item can be unstared by tapping the star icon again on the main view.

From the main view a token can be copied to the clipboard by tapping on it.

Known Limitations

At the moment the only way to insert new entries into the app is to insert the title and secret key by hand. It's not possible to use the QR-Codes some sites provide directly.
