Delete sign in option

I'm having problems with a few of my keys on my keyboard (8 out of the 10 keys get stuck) and need them to sign in. I've been unable to get onto my HP Spectra as a result. Until I can get the keys fixed I would like to delete sign-in. How can
I do it. There doesn't seem to be an option to cancel sign in.

Cannot sign in microsoft account.

My device: Lumia 520. GDR2.
I cannot sign in my Microsoft account on my device. It didnt say any error but Microsoft account is not listed in Email and account list. When I click add button, it will show microsoft account option but after press sign in, it is still not shown in email
and account. Another problem is i cannot delete facebook account. Error code: 0x83cf1202. I have tried as suggested here: http://support.microsoft.com/kb/2475837/en-us#step0x83cf1202 but as my Microsoft account is not shown, I cannot do step 6.

Any suggestion?
