The pass account was usually used by novel websites or online reading platforms to identify the user. It was usually a combination of numbers or letters, similar to the user's username. The password of the pass account was usually a security mechanism provided by the platform to protect the security of the user account. The user cannot set the account number and password for the pass. When logging in to the pass account, the user needs to provide corresponding identification information such as username, ID card number or mobile phone number to verify his identity.
