The password-type fields are textboxes with particular characteristics, they do non display the content of the typed text and allow understanding the complexity level of the entered password.
The small bar displayed under the typed text, expresses the password complexity basing the rating scale on five levels highlighted in five colors: 

• Very weak (Red);
• Weak (dark Red);
• Reasonable (Orange);
• Strong (Blue);
• Very strong (Green).

Example of textbox for entering passwords with complexity rating scale bar

In some cases, such as the insertion of system users, where a minimum level of password complexity is defined by the administrator, also the textbox color initially assumes a different color in order to make the user understand that the password entered does not yet meet the minimum requirements.
