Is it possible for a hacker to access and Instagram account if they only know your mobile number and not any of your email addresses? Would they need to be in physical possession of the phone or could they possibly access it remotely?
I was attacked like this recently and my phone was bursting with attempts to get my code to access my account. I immediately thought it was an ex and decided to check by logging into someone else's account. I tried but couldn't and when I entered my details I pressed 'forgot password'. I could see what number the account was linked to. This is how scammers work, even if you have no enemies, they can find out your phone number by pressing this combination of keys. I specially installed the sms receive germany service so that no one can steal my code or account. A foreign number guarantees at least some security
So I was attacked when the world situation started to be unclear recently. I tried to give a different phone number everywhere so I wouldn't get hacked. I bought several different numbers on purpose, so as to draw attention away from myself. I was hunting for US numbers, maybe there is a big demand for them now. But it's not so easy on Instagram unless it's tied to Facebook.
