Dear people who design web sites with logins:
It is a perfectly normal occurrence for me to log in to your web site from a different computer than the one I used last. It is not a cause for alarm. Being able to do that is arguably the whole point of the internet. It's not supposed to matter where I am; only that I can prove *who* I am.
I shouldn't need to verify my identity with a text message or phone call every time. Verifying my identity is what my username & password are for.
