Was Your Yahoo! Password Exposed?

News broke late last night that the Yahoo Voices service was hacked, exposing more than 450,000 usernames and passwords. If you’d like to check whether your email address was included we’ve built this tool: Type in your username or email address and we’ll crawl the list for you.

(Note: We are not storing any of the data that you put into the tool.)

If you prefer to see the entire list, it was published by the hackers here. Note it is a large file and may take a while for your browser to load.

Yahoo is the most recent in a series of high profile hacks. LinkedIn, Last.fm , Eharmony and Formspring were also recently hacked, compromising millions more passwords.

Simple tips for creating stronger passwords

  • use a combination of letters, numbers and special characters, lowercase and uppercase
  • make it long; at least 8, preferably many more characters
  • use a passphrase instead of a word if that is easy to remember
  • avoid sequences such as 123456 or common dictionary words or common names

Why does it matter? This image from Thomas Baekdal shows how long it takes to hack passwords based on their composition:
