I know we’re being over-protective

I cannot access my hotmail anymore via my Mac.  When asked to sign in using username and password, the page diverts to "I know we're being over-protective" page and asks for an alternate email address so Microsoft can send a code.  I can do this correctly and then I am sent a code.  Once I go to enter the code, I receive an error message that says "sorry that is the wrong code".  I have also tried using my mobile phone as a text and as a call to receive a code.  That does not work either.  This is extremely frustrating, as I have not had access to hotmail for 2 weeks.  Can anybody help?
