Tutorial

Este MemberScript hace lo siguiente:


It selects the password input field using the attribute data-ms-member="password".


The generatePassword() function creates a 32-character password by combining:


La marca de tiempo actual convertida a base 36


16 caracteres aleatorios (letras, números y símbolos)


Establece la contraseña generada como valor del campo de entrada.


It blocks password managers by setting autocomplete="off".


It prevents editing by setting the input field as readonly.


Se añaden escuchadores de eventos adicionales para evitar copiar, pegar, arrastrar y abrir el menú contextual en el campo de contraseña.


To use this script, include it in your HTML file and ensure you have an input field with the attribute data-ms-member="password" where you want the password to be generated.
