A software application providing two-factor authentication on devices utilizing the Android operating system, functions by generating time-based or event-based codes. These codes are used in conjunction with a username and password to verify a user’s identity when accessing protected resources, such as corporate networks or online accounts. One example would be accessing a virtual private network (VPN) from a mobile phone, requiring both a password and a one-time code generated by this type of application.
The employment of such applications significantly strengthens security by adding an extra layer of protection against unauthorized access. This mitigates the risks associated with compromised passwords, phishing attacks, and other credential-based threats. Historically, physical tokens were common, but software-based solutions offer increased convenience and reduced administrative overhead for managing authentication credentials. This shift has been driven by the proliferation of mobile devices and the need for secure remote access to sensitive information.
