My partner stayed in the hotel and received the verification code.

It is normal.

If his mobile phone number is bound and you do not log in using the mobile phone where his mobile card is located, you will receive a verification prompt every time you log in. This is for security.

Now the real-name system for the Internet and merchants is advancing. Therefore, whether it is an online forum or an offline hotel, real-name registration is required, so a mobile phone number and verification code are required, which is normal. Even if you don't stay in a hotel, if you register on the hotel's official website, you will get a verification code, or there will be promotions pushed by the APP.
