Hi Julee. Your browser can save your log-in info, that includes your email address and password. There are also apps that can help you with that. Did a quick Google search and found these: Keeper Password Manager (link) and LastPass Password Manager (link)
Visit Google Play store to find more apps of the same purpose.
Hope this helps!
