Galaxy watch 5 pro already paired to my phone is detected by others

[doobydude]

Is it normal for my watch 5 pro to be detectable via my GFs Bluetooth when my watch is already paired to my Z fold 3. Is someone pretending to be my galaxy watch 5 pro to be able to recieve 2FA codes??

It might be normal, if your gf has her BT always scanning & if your watch is in "discover mode". 

Bluetooth has a fairly limited range, maybe around 30' so it's pretty unlikely that someone is trying to do anything nefarious.

Hi, as suggested by RedDogRabbit there is a chance that your watch might detected by other devices, if it is in discoverable mode.
