Bind phone number to account

Hello, I currently have a SecondMeWeb account registered with the email address: iboceo8@gmail.com现在希望在App端使用手机号登录. However, I cannot find the option to link a mobile number within the account settings on the web platform. I would like to inquire: 1) Is it possible to link a mobile number to my current email account? 2) If backend processing is required, could you assist with linking or merging accounts? My mobile number is [Mobile Number]. Please advise on the specific steps to follow. Thank you for your support!
