Regarding the change of phone number for users who are currently using phone number login option, please be noted that users logging in with their existing phone number will go through the following steps when requesting a change to a new phone number.
- If you send us your previously verified phone number and email address, we will check if the information matches and then send you a verification code to the email address you shared.
- If you get back to us with the verification code you received, we will change your number after checking whether the verification code matches.
- Please be noted that only users who have received notification that the change has been completed can now change their phone number by attempting SMS login with a new phone number → verification → email verification → login completion.
