Touch ID

Force authentication from your iMessage recipient with MsgL0ck

Some people take their privacy more seriously than others, and a new iMessage extension dubbed MsgL0ck by iOS developer Simon Andersson takes that sentiment into consideration.

MsgL0ck lets the sender require authentication from the iMessage recipient before they can read the message. In Apple-speak, this means providing a fingerprint for Touch ID or a facial scan for Face ID (or a passcode if the recipient has neither).
