SketchUp Pro Authorisation Error - Delete login_session.dat

If logging out and back into SketchUp does not resolve authorisation errors, you can completely reset the sign in state by deleting the login_session.dat file.

Mac OS
For Mac users, locate the login_session.dat file in your hidden Library folder. 
  1. Go to 'Finder' and open the 'Users Folder'
  2. To see hidden folders press Command + Shift + . (Full stop/period)
  3. The path to find this file should be Users/USERNAME/(Hidden/greyed out) Library/ApplicationSupport/SketchUp[Version Year]/login_session.dat


For Windows users the file is located in C:\Users\*USERNAME*\AppData\Roaming\SketchUp\SketchUp VERSION\SketchUp

You can quickly get to the folder with all versions by pasting %appdata%/sketchup into an file explorer address bar

You will need to repeat this for each version of SketchUp on the machine that is having issues to completely clear all log in information on that machine.
