Feb 7 (Reuters) - The U.S. Federal Reserve's operational abilities were not impaired by a recent breach of a Fed website by hackers, a top Fed official said on Thursday.

The website that was hacked had contact information for banks to use during a natural disaster, Chicago Fed President Charles Evans said in an interview with CNBC.

'This isn't an internal operational website, the kind of thing that I have to log into; I've got multiple authentication keys, and that's highly secure,' he said. 'It didn't impair any of our operational abilities.'
