So I’ve been a Reddit user for over 5 years and I really haven’t contributed much, mostly just a “lurker”. Read about topics I’m interested in without much interaction aside from an occasional comment or upvote. Today I noticed that there is a second Reddit account liked to my profile that was created 13 days, which happens to be the last time I had to manually log in without FaceID… I’m almost wondering if I accidentally created a second account when trying to recover my password. Anyone have any ideas or guidance on how I unknowingly created another username?
