I have just overhauled my passwords using 1password - migrated from using memorable passwords in keepass to randomly generated ones in 1password (which feels safer and is far quicker) - but a couple of websites have a passcode but only ask for two, say the 3rd and 6th, letters and have a drop down boxes to select with.
I guess an autofill style selecting of the correct letter isn’t possible; I would guess that from a security standpoint that’s the whole point of the system – prevent people/bots from snooping/autofilling details. However, I think it would be good if, on pages that use this system, I could manually set a password that instead of autofilling in a dialogue box, just displayed the password of screen. That way I can quickly read my password and select the appropriate letters.
If this we’re possible, I have a further two requests:
1. Use a monospaced font to make counting along the password easy.
2. In stead of displaying the whole password, just display a horizontal list of monospaced numbers; then to display the corresponding letter of the password the user must mouse over or click on one. This is mainly for those using the system in public places.
