I’ve just had see that you must have an phone number to create a Twitter application.
Unfortunately this is not possible for me because I am only in possession of one phone number and this is linked to my private Twitter account.
Because I wanted to make for my website Twitter an application is it not possible because have no other numbers.
Can it please be solved that it is not required to use your phone to make an application, if necessary, you ensure that the DEV team first approves your application before your application works.
Sorry for my bad English, it’s not my native language.
