Hi @Greg Brown
Are the password characters you enter in password box not displayed or is there any error message?
Besides, can you enter passwords and login to OneDrive online successfully?
I suggest you go to Control Panel > User Accounts > Credential Manager.
Click on Windows Credentials > Check whether there is OneDrive Cached Credential.
If yes, please remove it.
It is also recommended to reset OneDrive to have a check.
