SketchUp Pro Authorisation Error - Delete login_session.dat

If deauthorising SketchUp does not resolve authorisation errors, you can completely reset the sign in state by deleting the login_session.dat file for all versions of SketchUp on all machines if using multiple of either.
  • For Mac users, locate the login_session.dat file in your hidden Library folder inside of your user area. (The path for this file should be /Users/*USERNAME*/Library/ApplicationSupport/SketchUp[Version Year]/login_session.dat)
    • To unhide the library folder, while in your username folder press Command, Shift and . (Full stop/period). The folder should be slightly greyed out. 






  • For Windows users the file is located in C:\Users\*USERNAME*\AppData\Roaming\SketchUp\SketchUp VERSION
    • AppData will be hidden, for Windows 11 select View > Show > Hidden Items.
    • For Windows 10 select View > Options > Change folder and search options. In the View tab > Advanced settings > Show hidden files, folders and drives > OK
