Kurzbeschreibung

For online probability surveys that recruit participants via postal invitation letters, passwords are used to manage access to the survey.These passwords serve several purposes, such as, blocking uninvited individuals, and preventing multiple submissions from the same individual. Research on web survey passwords has primarily focused on whether providing a password for survey access affects response rates. However, the chosen password strength, that is, length and complexity, may also affect response propensities . Password length refers to the number of characters in a password. Password complexity involves the set of characters from which the password can be derived (e.g., lowercase letters and numbers).
