  • (WP_User|WP_Error) WP_User object on success, WP_Error object for invalid or expired keys.

Codex:

Retrieves a user row based on password reset key and login.

A key is considered 'expired' if it exactly matches the value of the user_activation_key field, rather than being matched after going through the hashing process. This field is now hashed; old values are no longer accepted but have a different WP_Error code so good user feedback can be provided.
