1 question · Jump to Q&AAuthKu presents itself as a web-based two-factor authentication tool designed as a lighter alternative to native Android and Windows authenticator applications. The core value proposition revolves around privacy, with the company emphasizing that all data, including account names and secret keys, remains stored locally within the user's browser via local storage. This client-side architecture ensures that no secret keys are transmitted to external servers or third parties, which is a strong point for security-conscious users. The tool is described as a generator for OTPs, functioning as a direct replacement for traditional mobile apps. The interface appears to allow users to add accounts by name and input base32 secret keys, with automatic whitespace cleaning. While the privacy stance is clear, the tool's range is limited to this specific local storage model, meaning users must manage their own data persistence. The application is credited to Sofan Dianto, indicating a single-developer origin which may appeal to those preferring niche, privacy-focused utilities over large corporate software ecosystems.
The privacy policy is quite explicit about how data is handled, stating that all inputted account names and secret keys are stored locally in your browser. This client-side operation means no sensitive key data travels to the internet or third parties. However, the text does not specify what happens if you clear your browser cache or storage, nor does it detail if there is any automatic backup mechanism. For someone considering this company for sensitive credentials, the lack of clarity on local data persistence after a browser reset is a point to verify before relying on it as a primary backup solution for two-factor authentication keys.
It is really handy to have a web-based replacement for those heavy Android or Windows authenticator apps. The interface is clean and the privacy policy makes sense since everything stays client-side. I appreciate that no secret keys get sent to any third-party servers or databases, which gives me peace of mind when managing multiple accounts.
AuthKu keeps all secret keys in your browser's local storage, ensuring no data leaves your device during usage.
