There are 3 vertical dots upper right. If you hover over them t says customize and control Google Chrome. Click on them and drop down to settings. Now the second box says autofill. IN that box it says passwords. Click on it. You will see a lot of saved passwords. If you want to see the password of a site you click on that site and Chrome will ask you for "your password". [ and on a pc it asks for your pin.]
I am getting enter your password on the Chrome book and entering my gmail password same as password to enter Chromebook which says invalid.
That is the problem.
