So, many of you have alt accounts, right? I just got back into my account, which I was locked out of for a long time, and thought "Why not make an alt?" So I looked through mc.net and on mojang.com, and there was nothing I could find that was related to alt accounts. I can't buy Minecraft again at this moment, so theres no chance in paying again for a 2nd account.
What happened when you were locked out? Could you not reset your password or email or anything? It's just I'm having that problem right now.
I couldn't get in myself, but I had my brother get on and reset everything, mostly the security questions and email, because the questions didn't work at all, I had a paper with them too. If you don't have a brother or sister who plays Minecraft, send an email to mojang support, which is what I also did Hope this helps you get into the account.
