Q: How do I change the phone number associated to my keychain?

I called Apple. and the guy told me strait out that the phone number couldn't be changed. It didn't matter if the phone had been run over by a semi, had been stolen, lost, or was discarded, the security feature of iCloud prevented it. We screen shared, and I was even speaking to his head supervisor. The only solution that they could come up wt was turning off my keychain, so that I would stop getting the "verify the the two step verification" message. I don't know how any of you were able to change the phone # associated wt your account? I have a speech impediment, that makes speaking difficult, and spent an hour on the phone wt them. It wasn't an easy hour ...

I believe apple needs to train their staff .

All you need to do is when enter iCloud keychain it will ask for a code choose you forgot it then choose reset keychain. that is all.
