From what I&#x27;ve read in docs posted above, identity key is copied from S-Android to S-Desktop. If you lose S-Android, there are two possibilities.<p>1) Your keys are safe (device was encrypted and&#x2F;or you&#x27;ve wiped it remotely, whatever). In such situation you could be able to transfer keys from S-Desktop to new mobile. AFAIK there is no such functionality yet (remember, its Beta).<p>2) Your keys are not safe. In such case no recovery is possible. Notify all contacts about the fact that they should &quot;reset secure session&quot;, forgetting your Signal identity and establish new Signal identity.<p>Anyway, this is the only solution on market with secure chats and multi-device sync.
