Foil Auth

Your rating: None Average: 5 (17 votes)

Secure OTP (One-Time Password) generator for Sailfish OS.

Its functionality is similar to SailOTP except that Foil Auth keeps secret authentication keys encrypted with your Foil password. Supports both time-based (TOTP) and counter-based (HOTP) passwords. Tokens can be shared and imported via QR codes.

Foil password (and the RSA encryption key ~/.local/share/foil/foil.key) is shared with Foil Pics and Foil Notes. Encrypted authentication keys for OTP generation are stored in ~/Documents/FoilAuth.

The format of the encrypted file is described here.

Note that you can add your encrypted files and the Foil key to the backup with the help of My Backup app.

Good! Just don't lose your key and don't forget your password :)

Ok. I now understand how it works. I had to use inWebo anyway because the helpdesk was being stupid and rigid about this, but I understand what I have to do next time if I want to use the native app. Thanks !!!

Hello, I want to use Foil OTP to register my O365 account at work, but the IT helpdesk insists on going with an Android app called inWebo. I think that I could use Foil OTP instead, but I don't understand how OTP works technically so I am not sure. The helpdesk will not help me of course. Seeing an non Android / iOS device almost caused them a panic attack :-(

If you enter your foil password, select "Add Token" from the pulley menu and press "Scan QR code" button (they provided you the QR code, didn't they?), you should be able to import the token and use Foil Auth for authentication.

These "one time passwords" are essentially one long password (the secret= part of otpauth:// URL), out of which a shorter one is generated based on the current time. The algorithm implemented by Foil Auth is described here
