I’ve been using auto password and form fillers for over ten years and couldn’t live without them. I first started using RoboForm and now use a software program called LastPass.
It saves all my usernames and passwords and fills them in automatically when I choose the site from a drop down list attached to my browser.
Chrome is my browser of choice as it is clean, uncluttered looking and fast using multiple tabs.
One thing I always do with auto fill software is keep a record in hardcopy form or document form just in case for some reason software becomes corrupt or just disappears.
It hasn’t happened yet, but with my experience with computers and software, things can and will do the unexpected.
It will also keep your info in a secure encrypted vault.
Try it for yourself. The free version works great.
