So, SSA is "merging" with Login.gov, but in true gov't fashion in their effort to make things easier it's a complete cluster fuck. You can't change your address on Login.gov, and if you go to the old SSA.gov website you can't change your address there either. Thankfully I got a very pleasant lady on the phone who has attempted to change it for me, and she even admits it's a nightmare and a complete mess
