Key for Digital Authentication (KEYLA) is multifactor authentication in the form of a secure dynamic token that can be used as a One Time Password to verify a service. KEYLA uses a tokenization system to secure the OTP system and is a One Time ID which changes every 45 seconds to ensure the security of the user.

KEYLA uses a mobile number as the identity of the mobile device. This application can run offline without using an internet connection when it has passed the mobile number verification.
