Locker

Concerned about losing your phone and worried someone might figure out your unlock code and access your personal information? Locker is here to keep you safe.

Locker is as simple as it is brilliant. Specify the number of allowed attempts to unlock your phone. If the number of attempts exceeds this number the phone will be wiped and erased, protecting your personal information.

While Android does not offer the option to restrict the number of device unlock attempts directly, there is a device administration API that allows such a policy to be enforced through third party applications. This is exactly what Locker does.

Locker activates and enforces the security policy that will trigger a full system wipe when the specified number of unlock attempts have been exhausted. Depending on what lock screen application you are using the user will be presented with warning messages when the number of remaining attempts is 4 or less.

Locker is an essential app for anyone worried about their privacy. Its also 100% open source. The source and further documentation is available at https://github.com/Zyg0te/Locker
