Having more than one account is allowed, but only if you write to chess.com support and they approve of your second account. If your teacher wants to play you on chess.com, then that's not the same as you having two accounts though. You play on your account and your teacher creates their own account to play against you.
Why are you banning people from people playing on 2 accounts

bro he is banned for 1 year
You sure? That sounds oddly long. Maybe they did something else too.

If your teacher is the one with the other account, then that’s not your “second” account
how is he banned for a year… I’m starting to think this is ragebait

I actually didnt know that you have to contact them......

Well, that doesn’t sound like a good teacher anyway. If you want to improve I would recommend you to change teacher and not worry about him being banned for a year.
Odd title as he wasn’t banned for two accounts but for cheating.
why just stop my teacher cannot play now untill you stop
