The ACS APG8201 PINhandy 1 is a hardware-based one-time password (OTP) generator designed for two-factor authentication. The device generates time-based or event-based one-time passwords that can be used as an additional authentication factor beyond traditional username and password combinations. The device connects via USB interface and is compatible with Windows operating systems ranging from Windows XP through Windows 11, as well as Windows Server editions from 2003 through 2016 R2. It requires PC/SC driver installation for operation. As a physical token, the APG8201 provides an alternative to software-based OTP solutions by generating passwords on a dedicated hardware device. This approach reduces the risk of OTP interception through malware or phishing attacks that target software-based authenticators on compromised systems. The product is manufactured by ACS (Advanced Card Systems) and includes technical documentation such as product presentations, technical specifications, and user manuals. Driver support is provided through MSI installers for Windows platforms.
