GoKawiilGarmin Messenger reportedly restores chat history via SMS code alone
A Reddit user says they installed Garmin Messenger on a second phone, entered their existing number, verified it via SMS, and saw their full conversation history reappear without entering a Garmin account password. The second device then began sending and receiving messages, with no apparent way to view or disconnect other active sessions. Garmin has reportedly been notified but has not confirmed any fix.
