URLPattern: password property

Baseline 2025

Newly available

Since ⁨September 2025⁩, this feature works across the latest devices and browser versions. This feature might not work in older devices or browsers.

Note: This feature is available in Web Workers.

The password read-only property of the URLPattern interface is a string containing the pattern used to match the password part of a URL.

This is the normalized value of the password pattern passed to the constructor or the default value ("*"), which matches any password.

The following example creates a URLPattern object with correct-horse-battery{-staple}? for the password part and logs the property. This pattern matches the passwords correct-horse-battery and correct-horse-battery-staple.

const pattern = new URLPattern({ password: "correct-horse-battery{-staple}?" }); console.log(pattern.password); // 'correct-horse-battery{-staple}?' console.log(pattern.test("https://user:correct-horse-battery@example.com")); // true
