Does my logon phone number change when I update my mobile phone number?
Yes. Your mobile phone number is also used for logon and password recovery. After the change, use your new number to log on and receive verification codes.
Can I bind two mobile phone numbers to my account?
An Alibaba Cloud account supports binding only one mobile phone number. This number is used to receive messages and verify your identity (for example, to recover your password or change security settings), and also supports logon by verification code. You cannot bind two mobile phone numbers to the same account at the same time. If you want multiple people to receive notifications, go to Addresses and Contacts and add multiple notification contacts, each configured with its own phone number to receive different types of notifications.
Can I unbind or delete my mobile phone number?
No. Your mobile phone number is the secure phone number bound to your Alibaba Cloud account, and it is a core credential for identity verification and account security. It cannot be unbound or deleted. You can only replace it with a new number by following the procedure in this topic. Your account must always have a valid mobile phone number.
