An excellent place to start when experiencing issues signing into desktop applications is locating the credentials associated with that application in Windows Credential Manager and clearing them out.
Credential Manager lets you view and delete your saved credentials for signing in to websites, connected applications, and networks.
- To open Credential Manager, type credential manager in the search box on the taskbar and select Credential Manager Control panel.
- Select Web Credentials or Windows Credentials to access the credentials you want to manage.
- Click the drop-down arrow next to the credential you wish to manage and click Remove.
