Unable to login to icloud account

Hk anu286,

It's good that you can log in successfully at the Apple website, so we can focus on the Mac.

Have you restarted your Mac since this started happening? If not, go ahead and do that, as a restart can resolve unexpected issues.

Restart your Mac

On your Mac, choose Apple menu  > Restart.

• If you don’t want app windows that are open to reopen when your Mac restarts, deselect “Reopen windows when logging back in.”

Shut down or restart your Mac - Apple Support

If still an issue, try logging in while starting up in safe mode:

How to use safe mode on your Mac - Apple Support

It may take longer to finish the start up, as safe mode does some system checks, and can sometimes resolve issues. You'll also see some differences in the display. This is expected with safe mode, and when you restart normally, they'll be gone. After trying to log in, restart normally.

If you're still not able to get that login to accept, we'd advise to contact Apple Support.

Apple Support

Take care!

Hey anu286,

How are you logging in to your iCloud account? Are you logging in from the direct website on from your Mac Preferences? If you haven't tried logging in from the direct website, let's try that first to make sure that you're entering in the correct login credentials. That website can be found here: Sign in to iCloud

Let us know how it goes!

Best regards.
