Mac timing out

Thanks for your response, Dave. I'll do some testing on my phone and computer, so I can give you an accurate of what is happening, and where, e.g., which device, browser, app, setting. I may be confusing locking vs.  timing out?

For now, I'll tell you that for my computer, I'm using both Chrome and Firefox with a 1Password extension, and on my phone, I'm using the app. I almost never login to the site directly. 

Thanks again!
