authentication
C1Formal/Technical
Definition
Meaning
The process of proving or verifying that something or someone is genuine, true, or valid.
In computing and security, it refers specifically to verifying the identity of a user, device, or system. In law and documentation, it involves the act of certifying a document as authentic.
Linguistics
Semantic Notes
Often confused with 'authorisation' (which is about permissions after identity is confirmed). 'Authentication' is the verification of identity; 'authorisation' is the granting of access rights.

Connotations
Neutral technical term in both. Perhaps slightly more associated with digital/cyber contexts in everyday understanding.
Frequency
Slightly higher frequency in AmE corpus, likely due to the larger volume of US tech industry discourse.

Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'аутентификация' (direct equivalent) and 'авторизация' (authorisation). The Russian borrowing is accurate but the conceptual pair is the same.
- Avoid using 'аттестация' (attestation/certification of skills) for technical authentication.
Common Mistakes
- Using 'authentication' when 'authorisation' is meant (e.g., 'The authentication to view the file was denied').
- Misspelling as 'authenfication' or 'autentication'.
- Using it as a verb ('I will authentication the user' – incorrect; use 'authenticate').
