How do I delete ALL Chrome/Google Account stored website passwords at once?

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?

Solution 1:

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.

Solution 2:

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 Advanced tab, then choose a time range. Choose "All time" if you want to delete all passwords. Click the checkbox for "Passwords and other sign-in data". Click the blue button "Clear data" and then wait:

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).
