Typically this is caused by either the wrong login URL being used or cached browser data confusing the system, most often resulting from having recently logged into a different ARIVE account on the same computer. In some cases it may also be caused by using the wrong login URL.
Solution:
Try logging in through an Incognito/Private Browsing window. If you are able to log in successfully through an incognito window but get an Unauthorized Access message when logging in through a regular browser window, you'll need to clear your browser cache and cookies (making sure to set the time period to All Time or Lifetime). Exactly how to do this varies slightly depending on your browser, see below for the most common ones.
Google Chrome:
Internet Explorer:
Safari:
Once you have cleared your browser cache and cookies, you should be able to log in successfully.
If you continue to encounter a problem, make sure that you are using your correct company login URL (ending in .myarive.com) and check your computer's Date & Time settings and ensure that Set Time Automatically is on, Set Time Zone Automatically is on, the correct time zone is being selected, and the time shown on your computer clock exactly matches the time shown on your mobile device. Click the Sync Now button if it does not.
