Facilitate response to password subset challenge
There are cases where a password challenge is based on a subset of password characters.
For example "Enter the 2nd, 4th and 7th characters of your password".
It would be useful to have a UI where the authorised password reveal (eye icon) is, as an option, accompanied by a way of easily identifying each character's offset with the associated character of the password.
For example, perhaps by displaying in a distinct and small font the character's position in vertical alignment with each associated password character.
This would help avoid the error-prone approach of counting along the password by eye for appropriate characters.
