Security code of Instagram

I recently got a new device and was trying to login my account on my new device I went in and and it said I needed a security code, so I went to my hotmail typed in the code correctly and it said it was not correct after I sent a another one and another and it showed the same code over and over again and of course it said it wasn't right I don't know if it was because I was using Hotmail for this or this is just Instagram's problem. Thanks for your kind help.
