CeWL can be used to generate a custom password list by crawling a website for words that match s specific criteria.
cewl -w customwordlist.txt -d 5 -m 7 www.techshizz.com
The above command will crawl www.techshizz.com, 5 pages deep for any word 7 letters long or greater.
This method can be effective as it builds a list of possible passwords that are specific to a certain industry.
(PS. Don’t bother trying this on my website – I can assure you my password is not on this website.)
