This feature would likely be available in only two places: the vault, and when creating a new entry. The standard “choose password” tab in the browser add-in would have no need for this.
I feel this is important for two reasons:
- A graphic green/yellow/red status of complexity or “password goodness” is highly contextual and dependent on the current crackability state of passwords, as well as being too simple. There is not much to say how one password ends up being “better” than the other.
- A raw number could easily be complimentary to a graphic complexity option, by providing a concrete magnitude of the password’s complexity. By this raw magnitude measurement, one could more clearly compare passwords for effectiveness.
As it is, I still frequently go back to KeePass to generate passwords, as it’s bit complexity feature gives me a much better “feel” for how appropriate any one auto-generated password will be, given the options selected and the restrictions of the website being signed up on.
