I hope everyone reading this post knows how easy it is for Yotta to open any account at any other brokerage with this information. From there, they could initiate a transfer from your OTHER (non-Yotta) brokerages and drain your account. It really is that easy with the in-kind (or ACAT) process. Even if Yotta isn't nefarious, they could be hacked and a bad actor could use your data to accomplish the same thing.
I recommend locking down all of your investment accounts, Fidelity specifically has a lockdown mode designed for this. You can still trade/add money/pay bills, but no one can drain your account just because they opened up another account with your SSN.
