Since websites using Two-Factor Authentication require a password and a code, it seems silly to only show the user one of these. Currently, I am using Google Authenticator for one time codes, but that means I need to open 1Password and Google Authenticator to sign in. I added my github two-fac to 1Password and added that to my Apple Watch. However, the watch only shows the one time code. This won't be a problem when I'm on my home computer and can use the browser extension to fill in the password, but if I'm away from home I would still need to take out my phone (which defeats the purpose of the watch app)
It would be nice to have a second screen in the watch app, so when you click on an entry it shows the one-time code (if one is set up) and you can swipe to the left (or tap, force touch, or whatever) to see a second screen with the password. This way it is still convenient for users with the browser extension, and usable by those without it.
