The strength of a password may be evaluated with the help of a password strength checker, which assigns a rating to the password depending on factors including its complexity and length. The software examines a password and reports on its strength in terms of preventing unwanted access to private data.
Users and organisations alike often make use of the checking of the strength of their passwords in order to ensure the security of their credentials. They may also be integrated in online and mobile applications to guarantee that users choose safe passwords before they are given access to private accounts or data. This might be done both online and on mobile devices.
