AccessSecurium on the App Store and Google Play 22/02/2016
AccessSecurium generates codes for a two-layers authentication, that provides higher security than a simple password request. This app generates a new code every 30 sec, which should be typed together with the password. Without these changing code, it is impossible to log in.
The app works even in airplane mode and does not require internet connection. Furthermore, the app can also be used for other purposes provided TOTP or HOTP protocol is supported.
