Hi Gabriel,
It sounds like your laptop might still be holding onto old account info, which could be causing the password and OneDrive issues. Here are a few quick steps you can try:
Clear saved credentials
- Open Credential Manager (search it in the Start menu).
- Go to Windows Credentials and remove anything related to your Microsoft account or OneDrive.
Reset OneDrive
- Press
Windows + R, type:%localappdata%\Microsoft\OneDrive\onedrive.exe /reset - Press Enter. This refreshes OneDrive and may fix the sign-in issue.
Remove and re-add your account
- Go to Settings > Accounts > Email & accounts.
- Remove the old account, restart your laptop, then add your new account.
Check your Authenticator app
- Make sure your new account is properly set up in the app.
- You can manage it at https://mysignins.microsoft.com.
Try signing in via browser
- Go to https://onedrive.live.com and sign in with your new account.
- If that works, the issue is likely just on your laptop.
If none of this help, it might be best to contact Microsoft Support directly since this involves a previously hacked account.
