@lisette11 a pattern screen lock is no more effort than a swipe and hardly anymore than no lock at all.
Unless you live in a very well secured home and never go out, having no security on your phone seems pretty risky, especially if you are storing logins to your financial institutions on it or use SMS 2FA.
Thanks for reporting the issue to us. If password is not shown in specific sites, it's because we follow the website's code definition. Some sites reject autofilling of password, so we respect site's definition. If you could tell us which sites are having the problem, we can check if it's defined so or not.
