- tialaramex 7y agoIf you are concerned about this you can PIN lock Signal. It will prompt you periodically to confirm you still remember your PIN. When you get a new phone (or somebody tries to SIM-jack you) the new phone needs the PIN which you clearly remember because you kept entering it before. If you stop answering the PIN confirmations eventually it expires and somebody with that number can sign up (and if they want, set a new PIN). Regardless of whether you use PIN locks your contacts will be shown that something about the other party in the conversation changed, if they use in-person confirmations of identity they'll be invited to perform that over again.
