How to Wear Your Password
summary
Claims a usable replacement for passwords via a smart bracelet with Bluetooth LE, an accelerometer and a clasp that breaks a circuit when opened; it acquires identity once when the clasp closes (authentication can be by phone, PIN or biometrics) and holds credentials until untethered. Protocols include pairing, credential management and accelerometer trace matching to prove intent for clicks or signatures. Notes: NIST’s 19-bit entropy, common passwords ≈10 bits, and ~3% of people have unusable fingerprints.
