my bank pw
Was the last 4 digits of my SSN for more than a decade(the default password they assigned at the time mid 90s).
It is one of the banks listed.
AFAIK none of my accounts ever been compromised on any site. I have unique passwords and email addresses for each site(and i run my own email server). All stored in ultra secure QUADRUPLE ROT13 encoded text files. Web browser runs as a more limited user account on my linux mint systems.
