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.
GoKawiil's interpretation of the reporting above, not reported fact.
Because phone numbers are routinely reassigned by carriers, relying solely on SMS verification could let a new owner of a recycled number access a previous owner's message history, according to the concern raised in the report. This is particularly sensitive for Garmin Messenger, which often carries location check-ins and travel plans; if such data were exposed, it could reveal where a past user had been or planned to go. It's worth noting the test described involved one person controlling both devices, so an actual recycled-number takeover has not been demonstrated.
- A user reportedly restored full Garmin Messenger chat history on a new phone using only SMS verification, no account password.
- The second phone could apparently send and receive messages with no visible way to view or remotely log out other sessions.
- Concerns center on recycled phone numbers potentially exposing sensitive location and travel data to new number owners, though this hasn't been demonstrated in practice.
