Problem
There is a lot of user confusion with user's passwords. Many users assume:
1) The password will be the same across devices (both extension and mobile)
2) MetaMask is able to recover their password if it is lost.
These are standard patterns for "Passwords" across web2. Typically to unlock a device, the unlock code is called "Pin", "Pin code", "Passcode" etc. And it is often not retrievable in the same way that a password is.
Solution
To match user's mental model we should use familiar language. We should update the terminology across extension and mobile from "password" to "device passcode" or "device pin" (although "pin" may be associated with numbers only)
