prohibit login by local phone number
Hello all
I am using iphone SE2 with version 15.6.
I am not sure does this function work out of China or not. I am in China, many APP have a feature call "use local phone number to login", user click this button then login success.
On the login windows, it will show my phone number with mask like 158****2333. I try to did some research, this function seems work and provided by ISP.
I am not sure how much information that APP had been obtain. I would like to use APP completely in private.
Please noted that this should not like "Apps Using Apple ID", please do not mix up.
May I have your advise how could I achieve this?
Thank you.
Best Regards.
