We find the K2A keyboard a little basic for day-to-day use as an Android keyboard. It can be installed alongside other keyboards, can be easily swapped in and out with other keyboards. ![]() There is no need for any form of custom integration or browser add-on. The keyboard is also good for Android integration, as it works with all apps. This can directly access the KeePass database and enter usernames and passwords into forms without the need to store data on Android’s clipboard. K2A solves this problem by providing its own keyboard. We found that, for example, auto-fill functions for applications could be abused to steal the stored secrets from the password manager application using 'hidden phishing' attacks.” “Many apps completely ignore the problem of clipboard sniffing, meaning that there is no cleanup of the clipboard after credentials have been copied into it. This allows you to copy and paste usernames and passwords from an opened KeePass database to the app or webpage where they are needed. Most Android password managers (including most KeePass ports) work using Android’s built-in clipboard function. This is not as secure as K2A keyboard solution but does minimize the problem. For anyone who is wary of Google, I recommend using either KeePass DX or KeePass Droid instead.īoth of these apps are available from F-Droid and mitigate the clipboard problem with a clipboard timeout. We are comfortable with the trade-off between this risk and the advantages listed above. This means that, in theory, Google could slip malicious code into an update at any time. The main downside of K2A is that it is only available via the Google Play Store, and is therefore updated via Google Play Services. Both of these advantages are related to K2A's custom keyboard feature (see below). It does not rely on Android’s insecure clipboard function to work.Or, indeed, than most commercials products we have reviewed. It has much better Android integration than other Keepass ports.Most of these are open source and can open and manipulate regular KeePass files. Try, you will be informed when the user opens, closes, locks or unlocks the database including the file name information.There are a number of KeePass ports for Android. Then, wherever appropriate in your app, do something like this: To implement this, simply follow the steps descrIbed above in the sections Preparation and Authorization. in the latter case KP2A will offer to add entry information so that the entry will be found automatically next time). User action is only required if the KP2A database is locked (user will usually unlock it with the short QuickUnlock code) or if no matching entry is found (user can then create a new entry or select an existing one. KP2A 0.9.4 adds a great opportunity for third party apps: Instead of prompting the user to enter credentials or a passphrase, the app should try to get the data from KP2A if it is installed: If the user grants (or previously granted) access for the app, KP2A will automatically retrieve the matching entry. Please see the sample plugin “PluginA” for a simple example on how to do this: In addition, it is even possible to add new fields or modify existing fields. This is done, for example, by the QR plugin ( ). You can add menu options for the full entry or for individual fields of the entry when displayed to the user. These strings will be displayed to the user when KP2A asks if access should be granted. The Great PluginA Test plugin to demonstrate how plugins work (your-name-here) To tell Kp2a that you’re a plug-in, you need to add a simple BroadcastReceiver like this: As not every app/plug-in requires access to all information, you must specify which scopes are required by your app. Before your app/plug-in gets any information from KP2A, the user will have to grant your app/plug-in access to KP2A. Keepass2Android stores very sensitive user data and therefore implements a plug-in authorization scheme based on broadcasts sent between the plug-in and the host app (=Keepass2Android or Keepass2Android Offline). Now add a reference to the PluginSDK library from your existing app or add a new plug-in app and then add the reference. You should be able to build this library project. Preparationsįirst check out the source code and import the Keepass2AndroidPluginSDK from into your workspace. In case you have any questions, please contact me. Please follow the steps below to get started. ![]() How to create a plug-in or connect from your appĬreating a plug-in for Keepass2Android or enabling your app to query credentials from Keepass2Android is pretty simple.
