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.

Scott

I think this question might be conflating an Apple ID feature that is available in a few places, including China.


Use your mobile phone number as your Apple ID - Apple Support


With the Apple ID usage, using the mobile number as an Apple ID is optional. Not required.


I don't know of a way to get a unique identifier such as a mobile number, IMEI, Wi-Fi MAC, or device serial number from within an iPhone or iPad app, absent an iOS or iPadOS exploit. Apple deliberately blocks app access to a whole lot of identifying information that can be used for tracking. In response, the ad networks and ad trackers can and do strive to get better here too, and can track online identities indirectly. Online privacy is hard.


Some or all of this may or will work differently in China, given the legal and network environments.
