A password generator has the following components.Ī set of input values is used to determine the password for a site some must be site-specific so the generated password is site-specific.

Clearly this password also needs to be available to the web site authenticating the user the registration step, in which the password is set up, is discussed further in Sect. It generates, on demand, a site-unique password for use in authentication. 2.1 A ModelĪ password generator is functionality on an end-user platform to support password-based user authentication to a remote server (assumed to be a web site). The schemes have been briefly considered previously by McCarney under the name generative password managers. We focus on the general properties of such schemes and options for operation. The term has also been used to describe the generation random or pseudorandom passwords which a user must remember however, we use the term for schemes that generate a password in a repeatable way. Password generators simplify user password management by generating site-specific passwords on demand from a small set of inputs. This is the first time these schemes have been considered in a unified way. The main purposes of this paper are to (a) provide a general model for password generation schemes, and (b) use the model to propose a new system combining the best features of existing schemes. A number of schemes have been proposed but, apart from a brief summary by McCarney, they have not been studied in a more general setting. Īn alternative approach, which we consider here, involves generating site-specific passwords on demand from a combination of inputs, including those supplied by the user and those based on the site itself. However, if passwords are stored ‘in the cloud’, then there is a danger of compromise through poorly configured and managed servers. Passwords stored on a user platform restrict user mobility, since they are not available when a user switches platform, e.g. However, the shortcomings of password managers have also been widely documented (see, e.g., McCarney ). Passwords can be stored either locally or on a trusted server most browsers provide a local-storage password manager. A password manager stores user passwords and produces them when required (e.g.

We focus here on an important practical matter, namely how to make password-based user authentication to a website both more secure and more convenient.Īn important class of schemes designed to ease password use are password managers (what McCarney calls retrieval password managers). Given their current and likely future wide use, finding ways of improving the use and management of passwords remains a vitally important issue. as supported by protocols such as FIDO UAF ), but it seems likely that it will be some time before passwords are relegated to history. There are many potential replacement technologies, including combinations of biometrics and trusted personal devices (e.g. Passwords remain a very widely used method for user authentication, despite widely shared concerns about the level of security they provide.
