I have read other questions and replies, but still do not see a definite answer.  I was planning to upgrade my desktop file to 2021, but am waiting until I find this answer.  I have 1 desktop file on a stand alone desktop computer.  I am the only user.  I do NOT use any other Intuit services or keep any sensitive data in my file.  Will I be required to have an Intuit account and log into it to use my data file on my computer? or is this requirement only for users of connected services?
