DEPRECATED! Chrome now has password export built in.

backup_chrome_63_saved_passwords.js

// 1. Open: chrome://settings/passwords
// 2. Open Chrome developer tools (using F12 or Ctrl+Shift+i).
// 3. Run the following code in the console tab.
// 4. Copy output in a text file and save it somewhere safe!

    const asyncForEach = (array, done, iterator) => {
        let i = 0
        let next = err => {
            if (err) {

                setTimeout(() => {

    settingsPage = Polymer.dom(settingsUi[0].shadowRoot)
    container = settingsPage.querySelector("#container")
    settingsPasswordsAndForms = Polymer.dom(
        Polymer.dom(
            Polymer.dom(
                settingsPage.querySelector("#main").shadowRoot
            ).querySelector("settings-basic-page").shadowRoot
        ).querySelector("settings-passwords-and-forms-page").shadowRoot
    )
    page = settingsPasswordsAndForms.querySelector("passwords-section")
        .shadowRoot
    passwordSection = Polymer.dom(
        settingsPasswordsAndForms.querySelector("#pages")
    ).querySelector("#passwordSection")
    list = Polymer.dom(page).querySelector("iron-list")
    passwordItems = list.get("items")

    asyncForEach(
        passwordItems,
        () => {
            console.log(JSON.stringify(passwordItems, null, 4))
            // Now you can save the output in a text file!
        },
        (item, index, next) => {
            passwordSection.passwordManager_.getPlaintextPassword(
                index,
                (item) => {
                    passwordItems[index].password = item.plaintextPassword
                    next()
                }.bind(passwordSection)
            )
        }
    )
})()

Thanks for the code - however, it failed to execute for me, with the following error:
Uncaught TypeError: Cannot read property 'shadowRoot' of null

Any ideas?

Worked for me on latest Chrome. Thanks.

Thanks! Work on chrome 63.0.3239.132 on osx 10.13.2

Worked perfectly on Chrome 63.0.3239.132 on Win 7 64
Appreciate it man, thanks~!

To get a csv for 1password, i adapted the function with console.log to:

        function() {
				var txt = "";
				for (i = 0; i < passwordItems.length; i++) {
				var user = passwordItems[i].entry.loginPair.username;
				var pw = passwordItems[i].password;
				var url = passwordItems[i].entry.loginPair.urls.origin;
				// 1pw csv login
				txt += (url+','+url+','+user+','+pw+',\n');
				}
            console.log(txt);
        },

(quick hack, probably not ideal. you can play around with the urls.shown and urls.link too)

Hi How to import the file in another system please ?

@gregh747, you have to copy and paste it to a file manually. But, Chrome now has a password export built in, and this no longer works.
