Description

1password and Apple support options for automatic password generation for this they are using option password rules
e.q.
<input type="password" passwordrules="minlength: 8; maxlength: 36; required: lower; required: upper; required: digit; required: [-];">
it will allow automatically generate password like: "suhxe6-buwBum-zakvab", "hegxop-6ranqa-dIzkem"
All of this provides easier path for users who struggle to generate suitable password

• added option "passwordrules" to attributes supported by View/Helper/Password
• in order to reproduce build element password with password rules attribute
• expectation: view/helper/password renders option passwordrules appear
• tests to cover this case - added

To be honest, I'm not enthusiast about this: https://github.com/mozilla/standards-positions/pull/402/files

Even though I really like the fact that the possible attributes are kept up to date, but the current status of the passwordrules attribute is only a proposal. (See: whatwg/html#3518)

If the attribute is needed then it can be added as a valid attribute to the view helper. A factory or delegator can help here.

Safari is already support it, other browsers are coming

other browsers are coming

Mozilla considers it harmful as per link https://github.com/mozilla/standards-positions/pull/402/files :\

Can totally stay behind Mozilla's choice here.
