Methods and apparatus to manage password security

Abstract

Methods, apparatus, systems and articles of manufacture are disclosed to manage password security. An example apparatus includes means for invoking a provisional transmission block of a password associated with a user in response to detecting entry of the password, the password identified as new or changing and means for identifying a service category type associated with the password, the service category type associated with a threshold, the threshold determined by a security risk for the service category. The apparatus further includes means for retrieving a list of password hash values associated with previously used passwords associated with the user, means for comparing the list of password hash values to a hash of the password to determine a count of a number of times the hash value of the password matches a hash value on the list of password hash values. The apparatus further includes means for invoking a permanent block of the password when the count does not satisfy the threshold and means for releasing the provisional block of the password when the count satisfies the threshold.

Dependencies are inferred from the claim text.
