The autocomplete attribute specifies whether or not an input field should have autocomplete enabled.
Autocomplete allows the browser to predict the value. When a user starts to type in a field, the browser should display options to fill in the field, based on earlier typed values.
But sometimes (for security reasons, etc.) some HTML forms are setting the autocomplete=“off” attribute which do not allow a browser to auto-fill these forms - and Bitwarden should not ignore this attribute too.
