There are different policies for the generation of secure passwords. However, one of the biggest challenges is to memorize all these complex passwords. Password manager applications are a promising way of storing all sensitive passwords cryptographically secure. Accessing these passwords is only possible if the user enters a secret master password. At first sight, the requirements for a password manager application seem simple: Storing the passwords of a user centralized in a secure and confidential way. However, how is the reality on mobile, password manger applications, especially on Android? Applications vendors advertise their password manager applications as “bank-level” or “military-grade” secure. However, can users be sure that their secrets are actually stored securely? Despite the vendors’ claims, is it nevertheless possible to obtain access to the stored credentials?
In order to answer these questions, we performed a security analysis on the most popular Android password manager applications from the Google Play Store based on download count. The overall results were extremely worrying and revealed that password manager applications, despite their claims, do not provide enough protection mechanisms for the stored passwords and credentials. Instead, they abuse the users` confidence and expose them to high risks.
