¿Cuál es la contraseña del Wi-Fi?

How it works

This question uses the interrogative pronoun 'cuál' (which/what) with the verb 'ser' to ask for specific information. It also features a mandatory prepositional contraction.

• cuál es: 'what is', used instead of 'qué es' when asking for a specific item from a set, like a password or phone number.
• la contraseña: 'the password'.
• del Wi-Fi: 'of the Wi-Fi', formed by combining the preposition 'de' and the masculine article 'el'.

Register and formality

Because this phrase contains no second-person pronouns or verbs, it is inherently neutral. You can use this exact wording whether you are addressing a friend (tú or vos) or a hotel receptionist (usted).

Common mistakes

English speakers often try to translate 'what is' literally as 'qué es'. In Spanish, 'qué es' asks for a definition (e.g., 'What is Wi-Fi?'), while 'cuál es' asks for a specific piece of information like a name, number, or password.

Notes

Follow-up after asking for Wi-Fi. Neutral everyday wording.
