One-Time Password Generator

The tool accepts a shared secret and parameters to compute OTPs using HOTP or TOTP. It follows standard RFC algorithms to produce codes suitable for MFA testing and scripting. This platform is intended for developers, QA engineers, security professionals, and IT admins who need reproducible OTPs without network calls. Conceptually, a secret is combined with a counter or timestamp, hashed with a chosen algorithm, and truncated to the requested digit length to yield a numeric code. The primary value lies in reproducibility, RFC-compliance, and offline testing capabilities. Use cases include validating MFA workflows in development environments, automating test suites that require OTPs, and simulating user logins in security demos. Unique value arises from offline determinism, explicit input control, and straightforward integration into testing pipelines. Core features include support for both HOTP and TOTP, configurable digits and algorithms, optional timestamp or counter inputs, and exportable results for audit trails. The tool is particularly helpful for teams integrating MFA in data-heavy workflows or when validating Tableau-driven dashboards that simulate authentication scenarios.
