Notable Points to stay in Mind:

  • In case, you forget your PIN and haven’t any access to your old device then you’ll need to wait 7 days for the Registration Lock to expire. Only then, you’ll be ready to log in to Signal and make a replacement PIN. So to get on the safe side, write down the PIN and store it in a safe place.
  • Currently, Signal doesn’t support Authenticator apps or offer any backup codes. you would like to memorize the PIN which can act as your 2FA key.
  • The PIN isn’t your screen lock or chat/backup restoration key for Signal. It’s used for Registration Lock and preserving your profile settings.
  • Setting up 2FA on Signal will protect you just in case someone manages to swap your SIM. Princeton University did an in-depth study and located that US carriers granted SIM swap requests even when the caller could answer just one authentication question. So you ought to ensure 2FA is turned on to stop any hijack attempts.
