Need to logn twice to Connect.garmin.com/modern.

I think it might be unique to you. In my case, not only do I not log in 2x, I never have to login.

What happens if you go to Connect through Express. Do you still have to login manually?

It sounds like a security setting in your computer related to storing cookies is getting in the way.

OK more information. I choose to store data from each Garmin device. I use a different email for each device so I Do NOT check autologon. Therefore I choose which device I am using and then logon as that user. Any device requires 2 logon attempts.

I have 2 accounts - one for a vivosmart and another for a vivofit.

In Express, I configured each device to login to the proper account directly. So if I go to Connect from the link in express to view data for that device, I am taken to the proper account without logging in at all.

I have no idea why you should have to log in twice unless you're initially seeing your cached information and the first login actually doesn't go anywhere.

If you want to avoid logging in at all, try using express as a launching pad.
