Thank you for bringing your question to the community! We know that there can be some very valuable content within your Constant Contact account, and for security reasons, our system will always log you out after it detects that you are not using the page. Most browsers however do have the option to save your login information, so re-opening the page should allow a speedy login, and that automatic log-out should not be happening while you're actively working.
Is this logout happening more often than you expected, or is it timing out while you're working?
