It's always a good idea to change any shared passwords.I've been trying to figure out the security impacts to end users. I should probably change my passwords for fun... I think my Garmin credentials can get people access to various newspapers, the Atlantic, a couple of libraries, and meal kit subscriptions? Lol
Hopefully, if Garmin is doing everything right (and the password isn't guessable), no one will be able to figure out your password. Unfortunately we already know Garmin did at least one thing wrong.
