No, I am pretty sure this is not an auto password manager as I do not have one my own PC and the issue is there.
I just erased all passwords for all sites and username on my own Chrome under OSX and deactivated all preferences for password on chrome : It is working fine. There are no ******** in profile modification.
I then activated only "Ask for password storage", asking not to store it. : It is working fine as well. There are no ******** in profile modification.
I then logout from the site and login again accepting password to be stored : It does not work properly. Password field shows ******. of course "verify password" and "curent password" fields are empty.
I have checked that there is not any auto pass extension on my Chrome.
