Every change takes the password's proof by its own proof key (the
recovery phrase's for a lost password) and a SimpleLogin sign-in of the
last ten minutes on the device (`KeysOwnerProof`, its attempt), as ADR
0017's take the password and a code. The sign-in is checked before the
proof and taken with the change, so a wrong proof leaves it standing and
each sign-in serves one change.
- `keys.set(attempt, setup, handle?)`: the first keys of an account that
SimpleLogin was added to (anonymous before, or signing in with GitHub
or a code), with the handle where it has none; the sign-in alone, as
there is no password to prove yet.
- `keys.changePassword`, `keys.beginPhrase` and `keys.resetPassword` (a
lost password, with the phrase): every other session ends, in every
service, as ADR 0017's change has it.
- `keys.setRecoveryKeys`: a new phrase.
- `account.delete(keysProof)`: an account without SRP's verifier deletes
itself with the proof and the sign-in; `requireOwnerToDelete` no longer
asks such an account for SRP.
- `newKeysPasswordDigest` on both sides, held to each other by a test; a
challenge purpose of its own for the phrase's proof while signed in.
- Members ask the register for all of it; `RemoteRegister` and the
instance API carry the five new operations and the deletion's proof.
