Minecraft – How to find lost account login email address


I got logged off Minecraft and couldn't remember which email I used to log back on. So I purchased another account. I was messing around with the launcher_profiles.json file by reading it in Windows 10 notepad and I read my new email among the data. I tried to do a system restore to read the file before it was written to my new account and still had the old data, but system restore is off by default in Windows 10.

Is there another log file that will contain all the emails that I used to successfully login in the past?

Find launcher_profiles.json.backup or launcher_profiles.json in your minecraft folder. Search for authenticationDatabase, under which there is a username field which contains your e-mail address.
