✕Common Mistakes
Überprüfe die Identität, bevor du öffnen.
After ‘bevor’ the verb must be at the end and conjugated: ‘öffnest’.
Überprüfen Sie die Identität, bevor du öffnest.
Mixing formal ‘Sie’ with informal ‘du’ is inconsistent; choose one register.
Die Identität prüfen, bevor du öffnest.
While understandable, the imperative requires the verb first: ‘Überprüfe die Identität…’. Using the infinitive loses the command tone.

Cultural Tip
In informal German the du‑imperative is common, but in a professional or customer‑facing context you would use the formal form: ‘Überprüfen Sie die Identität, bevor Sie öffnen.’ Also, ‘Identität prüfen’ is a standard collocation in security and IT contexts.
