HTML Anchor `password` Property: Link Password

The HTML Anchor password property is a read-only property that returns the password portion of the URL associated with an <a> (anchor) element. This property is useful for extracting and working with the password part of a URL in web applications.

What is the Anchor `password` Property?

The password property of the HTML <a> element provides access to the password component of the URL specified in the href attribute. This property is particularly useful when dealing with URLs that include authentication information.

Purpose of the Anchor `password` Property

The primary purpose of the password property is to allow developers to:

Extract the password from a URL for validation or processing.
Display the password (though this is generally discouraged due to security reasons).
Manipulate the password portion of a URL (though direct manipulation is not possible since the property is read-only).

Syntax

The syntax for accessing the password property of an anchor element is:

let password = anchorElement.password;

Where anchorElement is a reference to an HTML <a> element.

Return Value

A string representing the password part of the URL.
An empty string if the URL does not contain a password.

Examples

Let’s explore several examples demonstrating how to use the password property.

Basic Example

This example shows how to retrieve the password from a URL and display it.

<!DOCTYPE html>
<html>
<head>
    <title>HTML Anchor password Property Example</title>
</head>
<body>
    <a id="myAnchorPass" href="http://user:[email protected]">Example Link</a>
    <p id="passwordDisplayPass"></p>

    <script>
        const anchorPass = document.getElementById("myAnchorPass");
        const passwordDisplayPass = document.getElementById("passwordDisplayPass");

        const passwordPass = anchorPass.password;
        passwordDisplayPass.textContent = "Password: " + passwordPass;
    </script>
</body>
</html>

Output

Password: password

In this example, the script retrieves the password from the URL associated with the anchor element and displays it in a paragraph.

Example with No Password

This example shows how the password property returns an empty string when the URL does not contain a password.

<!DOCTYPE html>
<html>
<head>
    <title>HTML Anchor password Property Example</title>
</head>
<body>
    <a id="myAnchorPassNo" href="http://[email protected]">Example Link</a>
    <p id="passwordDisplayPassNo"></p>

    <script>
        const anchorPassNo = document.getElementById("myAnchorPassNo");
        const passwordDisplayPassNo = document.getElementById("passwordDisplayPassNo");

        const passwordPassNo = anchorPassNo.password;
        passwordDisplayPassNo.textContent = "Password: " + passwordPassNo;
    </script>
</body>
</html>

Output

Password:

Here, since the URL does not include a password, the password property returns an empty string.

Example with Complex URL

This example demonstrates the password property with a more complex URL.

<!DOCTYPE html>
<html>
<head>
    <title>HTML Anchor password Property Example</title>
</head>
<body>
    <a id="myAnchorPassComplex" href="https://user:[email protected]:8080/path/to/page?query=param#hash">Complex Link</a>
    <p id="passwordDisplayPassComplex"></p>

    <script>
        const anchorPassComplex = document.getElementById("myAnchorPassComplex");
        const passwordDisplayPassComplex = document.getElementById("passwordDisplayPassComplex");

        const passwordPassComplex = anchorPassComplex.password;
        passwordDisplayPassComplex.textContent = "Password: " + passwordPassComplex;
    </script>
</body>
</html>

Output

Password: complexPassword123

In this case, the script correctly extracts the complex password from the URL.

Use Cases

The password property can be used in various scenarios:

URL Parsing: Extracting the password from a URL for processing.
Security Auditing: Checking for passwords in URLs (though displaying or using them directly is discouraged).
Debugging: Displaying URL components for debugging purposes.

Important Considerations

Security: Avoid displaying or storing passwords directly, as this can lead to security vulnerabilities.
Read-Only: The password property is read-only, so you cannot directly modify the password of a URL using this property.
URL Format: The password property only works if the URL is correctly formatted with the password included.

Browser Support

The password property is supported by all major browsers, including:

Chrome
Firefox
Safari
Edge
Opera

Conclusion

The HTML Anchor password property is a useful tool for extracting the password component of a URL. While it has limited use cases due to security concerns, it can be valuable for URL parsing, security auditing, and debugging purposes. Always handle passwords with care and avoid displaying or storing them directly. 🛡️
