Common Pitfalls
Translation Traps (for Russian speakers)
- Not a direct equivalent of 'аутентифицировать' in all IT contexts; 'verify' or 'log in' might be more natural in casual speech.
- Do not confuse with 'authorize' (дать разрешение). Authenticate is about proving *who* you are; authorize is about what you are *allowed* to do.
Common Mistakes
- Using 'authenticate' when 'authorize' is meant (e.g., 'The system won't authenticate me to delete the file' – should be 'authorize').
- Pronouncing it as /ˈɔː.θən.tɪ.keɪt/ (wrong stress on first syllable).
