|Re: In an instant, retirement savings vanish|
IMHO...don't link them. Don't allow one account to know about another. Convienence could come at a steep price if someone accesses your accounts.
You will have to ask the online firm.
Watch for under $1 wire credit and debits. These are test signs of future bigger wires. It is how credit card firms flag fraud. Hackers do under $1 charges to see if it flies...then hit you for the max. if it does.
I try and think it from the hackers perspective on what I could do if I breached my account.
