- What methods are supported?
Every method that involves the use of a 8-digit numeric PIN, provided all the correct data is supplied. These are: _label_, _push-button_ and _display_. Note that the display method allows for a 4-digit numeric PIN to be used, but since the specification requires these types of PINs to be used only once, it would be useless to support them in pixiewps anyway.

The most recent version of pixiewps must be considered the most "correct" and "general". It may be slower or faster compared to older versions but that doesn't matter. Pixiewps tries to do as little work as possible to recover the correct PIN, but you have to keep in mind that it only sees numbers in input, and it may not always be possible for it to take the "shortest path". Because of that, some versions may have to do more work in order to work in all instances, more so if no `--mode` is specified.
It should be up to the user or the higher-level tool to detect the right vendor and supply the correct mode to pixiewps. This is fairly easy to do with a tool which uses monitor mode and can grab the vendor OUI tag from a beacon frame. When monitor mode is not an option, the user or tool can resort to the usual WPS fields like model, serial etc.
## Notes:
1. This may be not always true in the event it would be possible to crack the PIN and complete the protocol before a timeout from the Enrollee. This feature however is not supported in tools currently available.
