AustinN4, their website makes it super easy to do. They do ask for your full SSN, but it’s a secure website. And it will confirm the security locking code will be sent via snail mail. (Took a little longer than I was expecting but like the “big three”, I suspect they’re probably swamped with locking requests at the moment).
You're right.
Using Roboform, took less than 30 seconds
Now for the snail mail lottery ...
