OTPClient

OTPClient is a desktop application built for Linux to manage One-Time Password tokens, supporting both time-based TOTP and counter-based HOTP algorithms. The program stores all generated token secrets locally in an encrypted database, protecting sensitive authentication credentials from unauthorized access. Users can organize their tokens into custom categories and utilize a built-in search function to quickly locate specific entries during authentication workflows.

The interface allows for manual entry of secret keys or automatic addition via QR code scanning using screen capture or image files. It functions independently of cloud services, ensuring that authentication data remains entirely under user control on the local machine. The feature set focuses strictly on token storage, generation, and export capabilities without incorporating proprietary cloud synchronization protocols.
