I have hundreds of them, it takes .6 seconds to delete one in the browser and 3.7 seconds to delete one in the Google Account management page.

There has to be a way to remove all of them at once... right?

Found it. Clearing all the saved passwords in Chrome from Clear browsing data... also deletes the synced passwords in the Google Account. The setting can be revealed by clicking on the Advanced Tab.

The fastest way to clear all Chrome passwords is with this shortcut:
Ctrl+Shift+Delete

That'll open the "Clear browsing data" window. Click the checkbox for "Passwords". By default, it will clear passwords since "The beginning of time". Choose how long ago to delete passwords for:

It can take a long time to delete the passwords and other cached items (it took 20 minutes for my Chrome to clear 1200 passwords and 350MB cached pages/images).

Click the blue button "Clear Browsing Data" and then wait:

Based on the answer by @bill-mcgonigle I assume it would also be possible to just use the Chrome Console

function sleep(ms) { return new Promise(resolve => setTimeout(resolve, ms)); }

for (let button of window.document.querySelectorAll('div[role=grid] > div[jsmodel] > div[role=gridcell] > div[role=button]')) {

    if (typeof button != undefined) {

        button.click();

        sleep(3100);

    }

}

This worked for me, after the first time you run it, Google will ask for your password again. After that my 200+ passwords were deleted without any issue.

Please note there's a warning in the console to understand the risk of running anything there. Be advised, read the above carefully to understand what you run.

Clarification:

// function to wait for 3 seconds before clicking the next delete button

function sleep(ms) { return new Promise(resolve => setTimeout(resolve, ms)); }

// start a loop iteration of all buttons inside the password grid

// please note there are two grids on the page

for (let button of window.document.querySelectorAll('div[role=grid] > div[jsmodel] > div[role=gridcell] > div[role=button]')) {

    // in my debugging there was one undefined button

    if (typeof button != undefined) {

        // click that exact button element

        button.click();

        // wait for 3.1 seconds

        sleep(3100);

    }

}

I've run into this scenario where I only wanted to delete a large number of specific passwords. Finding no suitable alternative, I created a macro with Keyboard Maestro that deletes 10 at a time:

chrome remove bulk passwords.kmmacros

The file can be viewed for security purposes on Google Drive or in a text editor (the .kmmacros files are XML formatted) and can easily be modified to delete hundreds at a time.

All it does is clicks at the current mouse location, clicks 40 pixels below, and returns the cursor to the original location, repeating 9 more times.

For X11 systems, you can load passwords.google.com and on the saved passwords page put the mouse over the top trash-can icon and from a terminal do:

watch -n 3 xdotool click 1

and keep the mouse over the trash can icon until it's done - the next undeleted password will move up after each previous one has been deleted.

Now, Google seems to sign you out at 5 minutes sharp for each p.g.c session, so this method can only do a hundred at a time (my goodness, 20 years of saved passwords...) but it's less maddening than clicking each one individually. Google does appear to impose a 3-second delay between each delete event. I tried fiddling with random delays and mouse wiggles, but those don't affect the 5-minute timeout.

This method also works for the 'never save passwords for ...' section, but it will error out if any of those are of the chrome-extension:// protocol type, in which case you will need to move the cursor down one manually.

I did do the Chrome-side tip given above to delete all passwords, but as soon as I turned on an old device it uploaded them all again. :angry react:

That Google makes this so darn hard to do is probably reason enough to think that it's a good idea.

I'm having a bizarre do-loop problem that's similar to this, would really welcome bigger brains to help!

So due to a TSA snafu, I don't have my laptop anymore. I'm concerned about Chrome sync'ed passwords (as Chrome doesn't ask for 2-step verification to show passwords, just the computer password, and I'm assuming worst-case-scenario someone brute-forces my Mac computer password.)

I found the following instructions online and followed them:
- logged out of sessions remotely through "details" under Gmail
- delete all the passwords on Chrome primary instance
- then unsync under settings (uncheck each sync parameter for apps, history, etc.)
- then reset sync to clear the Google server
- set a new sync password

I did all of this--and to doublecheck, I went to my secondary PC with Chrome, which was indeed logged out, but had the old passwords (I'm guessing as a local copy.) As soon as I logged back in, rather than clear out all the passwords, sync repopulated my Primary computer with the old passwords. So my understanding now is, as long as there's an instance of Chrome with old passwords on it, as soon as I resync, it'll autopopulate.

So the question is, is there no way to actually delete and keep cleared all the passwords Google Chrome has stored for me, across any sync'ed Chrome instance, such that that's the official record. Or am I going to have to go to each computer I own with Chrome and manually delete all saved passwords?

It seems insane that any old instance, rather than take instruction from the newest Chrome instance, can overwrite and repopulate passwords.
