CVCheck's Password Policy
Our password policy was chosen to comply with the security recommendations by the National Institute of Standards and Technology of the US Department of Commerce (NIST). NIST recommends a password policy that supports passwords with a minimum of 8 characters in length AND never having been listed or exposed due to a data breach of any internet site.
Hackers often breach accounts and gain illegal access by making use of lists of passwords that are published and built from previous system breaches. These lists contain millions of passwords that have been employed by other uses (perhaps, even you) on various systems around the world.
