this is very very confused.

the key you use in Matrix to get at your historical messages /is/ your security passphrase/key (assuming you set it up).

the vector.im identity server is just a phonebook to let people discover you based on email address if you so desire.

the UX in Element is clearly a disaster, given nightmarish confusions like this. we have tried to fix it in Element X and stuff like https://github.com/matrix-org/matrix-spec-proposals/blob/and... which is looking promising
