LastPass has seven trackers in it's Android App

A security researcher has recommended against using the LastPass password manager Android app after noting seven embedded trackers. The software's maker says users can opt out if they want.

German infosec bod Mike Kuketz spotted LastPass's trackers in analysis produced by Exodus, which describes itself as "a non-profit organization led by hacktivists [whose] purpose is to help people get a better understanding of the Android applications tracking issues."

The Exodus report on LastPass shows seven trackers in the Android app, including four from Google for the purpose of analytics and crash reporting, as well as others from AppsFlyer, MixPanel, and Segment. Segment, for instance, gathers data for marketing teams, and claims to offer a "single view of the customer", profiling users and connecting their activity across different platforms, presumably for tailored adverts.

LastPass has many free users – is it a problem if its owner seeks to monetise them in some way? Kuketz said it is. Typically, the way trackers like this work is that the developer compiles code from the tracking provider into their application. The gathered information can be used to build up a profile of the user's interests from their activities, and target them with ads.

Even the app developers do not know what data is collected and transmitted to the third-party providers, said Kuketz, and the integration of proprietary code could introduce security risks and unexpected behaviour, as well as being a privacy risk. These things do not belong in password managers, which are security-critical, he said.

Kuketz also investigated what data is transmitted by inspecting the network traffic. He found that this included details about the device being used, the mobile operator, the type of LastPass account, the Google Advertising ID (which can connect data about the user across different apps). During use, the data also shows when new passwords are created and what type they are. Kuketz did not suggest that actual passwords or usernames are transmitted, but did note the absence of any opt-out dialogs, or information for the user about the data being sent to third parties. In his view, the presence of the trackers demonstrates a suboptimal attitude to security. Kuketz recommended changing to a different password manager, such as the open-source KeePass.

Do all password apps contain such trackers? Not according to Exodus. 1Password has none. KeePass has none. The open-source Bitwarden has two for Google Firebase analytics and Microsoft Visual Studio crash reporting. Dashlane has four. LastPass does appear to have more than its rivals. And yes, lots of smartphone apps have trackers: today, we're talking about LastPass.


A LastPass spokesperson told us: "No sensitive personally identifiable user data or vault activity could be passed through these trackers. These trackers collect limited aggregated statistical data about how you use LastPass which is used to help us improve and optimize the product.

"All LastPass users, regardless of browser or device, are given the option to opt-out of these analytics in their LastPass Privacy Settings, located in their account here: Account Settings > Show Advanced Settings > Privacy. We are continuously reviewing our existing processes and working to make them better to comply, and exceed, the requirements of current applicable data protection standards."
