Hello @Paul Clayton Jr,
My name is Henry and I am happy to assist with your inquiry, and appreciate you contacting LastPass Support!
You can autofill your passwords for apps installed in your computer using the LastPass for Windows Desktop app. However, auto-save is not available in this case, you will need to manually store the app password.
Please let me know if this worked or if further assistance is required.
Thank you,
Henry | Customer Care
