Cross-Browser and Device Security Testing: Verifying Secure Handling of Credentials
Cross-browser and cross-device testing is like ensuring your secure credentials are handled with care, no matter where they’re used. Think of it like baking a cake — you need to make sure that your recipe (secure login and credentials handling) works in every kitchen (browser or device) without compromising the ingredients (your sensitive data).
The Challenge: Different Browsers, Different Security Weaknesses
Imagine you’re trying to bake a cake in different ovens. Some ovens are more reliable than others, and some might be too hot, while others might not heat up enough.
Similarly, when dealing with cross-browser and cross-device security testing, browsers and devices have different ways of handling security and credential management. This means that a feature might work perfectly on one browser but fail miserably on another.
One example comes from my time testing an e-commerce platform. I was testing the login flow across browsers and devices, and Chrome worked flawlessly.
However, when I tested it on Safari, I found that credentials were stored in clear text in localStorage, making them easily accessible to anyone with access to the browser’s developer tools…
