About Sign In Pro
Sign In Pro is the ultimate in-page credentials manager tailored specifically for developers, QA testers, and power users who frequently switch between multiple accounts or test environments.
Tired of digging through heavy password managers, copying and pasting credentials, or losing your test accounts? Sign In Pro streamlines your workflow by injecting a sleek, non-intrusive floating widget directly onto any webpage.
Key Features:
• Quick Auto-Fill: Access your saved credentials instantly. Click on a saved profile in the floating widget to automatically inject the username and password directly into the login form without switching tabs.
• Smart DOM Picker: No more manual selector configuration. Visually pick the username and password input fields on any website to map your credentials effortlessly.
• Secure Local Storage: Your data stays with you. All credentials are saved securely within your browser's local extension storage. We do not track, collect, or transmit your data to any external servers.
• Import & Export: Easily back up your credentials to a JSON file and import them across different devices or testing environments using the dedicated Options page.
• Modern, Lightweight UI: Designed with a beautiful, responsive, and intuitive interface that uses Shadow DOM to prevent any styling conflicts with the websites you are testing.
• Privacy First: Requires minimal permissions and operates entirely offline.
