Can I access my wallet without 12 words or private key?
If there was a way to get access to your wallet without 12 phrases or private key, someone who's not you could get your funds and that would make the entire system unsecured. Without the 12 words and private key, you cannot get access to your wallet if you lose it.
ATTENTION!! 12 phrases and your private key to your wallet are secret information, keep them as securely as possible. Never reveal them to anyone or any online service. An attacker may get access to your secret information and steal your funds.
