Below is an example link that takes you directly to a dashboard without requiring login. Basically you must specify your company/account, and username & password in the URL. I recommend you minimize the risk by making sure the user has a role of READ-ONLY or just permissions to the dashboard(s) you want. I suggest you use a password that only uses URL friendly characters ( letters, numbers, and  _ – ~ and .  )

To get and build this URL, navigate to your desired dashboard and add the portion

?c=your_account&u=some_username&p=your_password

in the middle (after the index.jsp and before the #dashboard=XX)

EXAMPLE:
