Not allowed or not approved by the person or group that has power to decide.
Patrón de uso:
unauthorized [noun]; [something] is unauthorized
Error frecuente:
Learners sometimes think "unauthorized" simply means "bad" or "fake". It specifically means something is not allowed or not officially approved by someone in authority, which may or may not be illegal. Also, do not say *"not unauthorized"* when you mean *"authorized"*; use "authorized" or "official" instead.

done without legal or system permission
Used when someone uses a system, account, or thing without the legal right or required permission, often against rules or the law.
Patrón de uso:
unauthorized [access/use/transaction/disclosure]
Error frecuente:
Learners sometimes use only "illegal" for computer or banking problems, but in real use banks, websites, and policies often say "unauthorized access" or "unauthorized transactions" to stress missing permission or account holder agreement, not just criminal law. Also, avoid *"not authorized access"*; use the fixed collocation "unauthorized access".
Sinónimos
illegal (Stronger and broader; clearly states that the action breaks the law, while "unauthorized" focuses on lack of permission or right, which may be legal or contract-based.)
Antónimos
authorized (Indicates that the access or action has the proper legal or system permission.)
