I was tired of having to create multiple browser sessions for my multiple accounts, and also remembering the login information for them. So I created this free chrome extension for myself and you can use it too. It is safe to store your credentials as well as all the information is stored in your own browser. It is available at:
https://chromewebstore.google.com/detail/switchbro-save-broker-log/dckekpecmbghmgeglmbakfmjnikphfjn?hl=en&authuser=0
the code is also opensourced and available at:
