I deleted one I didn’t even remember having. Something I created back when I first got a smart phone and as much as I recall think I used it for the primary phone login account and had my separate emails just in the client.

Only got reminded of it when they sent an email to my main address saying it had been inactive for years and was going to be deleted anyhow, so went through this process where they unlocked it after a month of waiting to see what was in there before shutting it down. Was pretty much blank from the start so it doesn’t really matter if they actually deleted it or not.

How my main email got set as a recovery is another question, probably just many years back brain not being so good at keeping online identities siloed.
