[PATCH 0/4] Introducing external NFC devices as storage for tokens
by Petter Arvidsson 19 Jan '15

19 Jan '15

Hi (again) everyone, (As you might have noticed my previous patches got eaten by the mailer daemon :-) I have now split my patches in to additional commits and I hope they will be accepted by the system. I also agree with Nathaniel that they are way easier to follow now as well. For convenience I also include the original cover letter below.) My name is Petter and I am working for the Swedish company Fidesm AB. We are building a platform for managing Secure Elements (such as NFC cards) via the network. One of the first services that can be deliverd via our platform is an OTP application developed by Yubico (https://github.com/Yubico/ykneo-oath). To enable us to use this application to store our OTP credentials we wanted to integrate it into a good OTP Android App. This patch enables any supported external NFC token to be used with FreeOTP. Currently the only two tokens using ths protocol that we know of are the Fidesmo Card and the Yubico Yubikey. I am more than willing to add support for any other device which is using the same protocol. The strategy taken to integrate this into FreeOTP was first to generalize the TokenPersistence and Token classes to accomodate both internal and external tokens. This is the first commit/patch. On top of this the NFC functionality was built. To manage the NFC tag efficiently (i.e. not to have the user tap it more than neccessary), we decided to handle it only in the main activity. This required the other activities to return their results rather than manage the TokenPersistence directly. This is a very common pattern in Android and we believe that end result was actually quite nice, clearly separating managing the tokens from the other activities. If you want to try it out you will require an external NFC token. Please let me know if you want a Fidesmo Card and I can provide instructions on how to get one for free. As earlier stated it can also be tested with a Yubikey from Yubico. I hope you like the implementation and that you have some good feedack for me on what needs to be changed and improved! Please beware that I am a bit new to git send-email, so let me know if you want any changes to how the patches were generated.

Turn off automatic clipboard copy of code?
by Peter 12 Dec '14

12 Dec '14

Because my devotion to open source, I'm thrilled to have recently switched to FreeOTP from Google Authenticator. Being truly open source, FreeOTP appears to be a far better alternative than Google Authenticator. But I do have one concern: when I generate a code (on Android 4.4.4.) it not only displays the code but also copies it to the clipboard. Is it possible to turn off the copying to clipboard functionality? The reason I ask is that I recently read this article which I found disturbing: http://arstechnica.com/security/2014/11/using-a-password-manager-on-android… Hence, I'm being very careful with what I copy to my clipboard on my phone and would love to disable that specific funtion on FreeOTP. Is that possible? Or, being new to the app, perhaps I'm doing something wrong and there is a way for me to view the code without copying it at all? Any guidance appreciated. Many thanks, Peter

Use storage access framework to select image on kitkat
by Ruben Roy 27 Nov '14

27 Nov '14

Hi As of now, selecting an image is done from an activity where one has to view all images on the device at once. A better way would be to use the storage access framework on devices running kitkat and above. This has been fixed in issue 48: https://fedorahosted.org/freeotp/ticket/48 Ruben Roy

Crash at startup on Lollipop
by Anisse Astier 26 Nov '14

26 Nov '14

Hi, I opened a bug on trac, and I wanted to raise awareness about it: https://fedorahosted.org/freeotp/ticket/47 It's a crash at startup on Android 5, which might mean you're locked out of your configured accounts. Anyone had the time to look at it ? A quick analysis seems to show that View.setTag() isn't used properly. Best regards, -- Anisse

Set icon in QR for FreeOTP
by Sean Kavanagh 17 Nov '14

17 Nov '14

Hi, I enabled 2FA via TOTP in a project of mine for OpenShift. https://github.com/skavanagh/KeyBox-OpenShift I've been using the QR format like so https://code.google.com/p/google-authenticator/wiki/KeyUriFormat Everything works great!! .. but I was curious if there was a parameter to set the icon in the QR for FreeOTP?? Maybe by passing in a url to the icon or something?? Thanks, Sean
