This Chrome extension gives you the ability to store your login credentials for 3rd party services. It works by detecting if you're on a site where you need to log in and then choosing the account automatically. This means you can be logged into multiple websites at once, but just have to select the one you're currently on when you log in.

Features:

This extension uses the new OAuth login flow.

You can use this extension to:

Automatically switch to your Google account when logging in to a site.

Store your credentials in a Google Account.

Select the account you wish to log in to a site.
