How to store google account password on chrome? works on all sites except google sites

I am using different google accounts to manage google ads accounts, so I use chrome portable because it works faster than firefox portable.

On Firefox I was able to save the google account password and email and it was really helpful to save time when logging in

But on chrome seems that google has disabled that feature only for their sites.

Is there any solution to this?

I thought of finding or developing an unapproved chrome extension that I can install on earch portable and works like password manager (offline)

But is there any easier solution?
