Google Authenticator
wikipedia:Google Authenticator (2010) is a software-based authenticator by Google that implements two-step verification services using the Time-based One-time Password Algorithm (TOTP; specified in RFC 6238) and HMAC-based One-time Password algorithm (HOTP; specified in RFC 4226), for authenticating users of software applications.[1]
Google Authenticator was open-source until 2013 [2]
The Android OS allows apps to protect their users by blocking other apps from screenshotting their content. This is done by adding a "FLAG_SECURE" option inside the app's configuration.
