Cannot log into twitter on Iphone or computer


Basically got a new iphone on saturday, tried to log into my twitter on it but got a message saying need to make temporary password on computer, when i went to the computer it said i had to change password so i did but then it would not let me into my account taking me to a verification screen.

So now, when i try on iphone i get the make a temporary password message and when i try on the computer i get a screen saying:

We’ve sent a login verification request to the Twitter for iPhone app.
When you receive the request, accept it by clicking the checkmark button on your phone. You can also enter a backup code.

Didn’t receive a notification? You can check your login requests manually in the Twitter for iPhone app, under Me > Settings > Choose Account > Security > Login requests. Learn more
