Since Chrome 66, if you are using Chrome as your password manager you can export all your saved password to a plain CSV file that you can save for your own reference.
Here is how to do it.
Go to the Settings page, expand the Advanced and click Manage passwords under Passwords and forms section.
Then click the vertical 3-dot icon and Export passwords… icon that pops up.
A warning pops up to make sure you understand that the password you exported will be visible to anyone. Click Export Passwords… blue button when ready.
Type in your Windows credential if you are running Chrome on a Windows computer and your list of saved passwords will be exported in a plain CSV file.
