To find saved credentials on that Windows computer:
- On that PC, type Credential Manager in the taskbar search box.
- Select Credential Manager Control panel.
- Open Web Credentials or Windows Credentials.
- Look for the saved entry for the network computer, website, or app.
Credential Manager lets Windows view and delete saved credentials for websites, connected applications, and networks.
If the prompt is asking for the account name to use on that specific PC, the accepted guidance in Microsoft Q&A is to open Run with Win + R, run cmd /k whoami, and note the name shown after the backslash. That is the username to try for network sign-in.
If saved credentials are wrong, remove the matching entry under Windows Credentials and then reconnect so Windows prompts again for the correct sign-in.
