thinkorswim takes security very seriously. Security, however, is a two way street. Some security measures,
like SSL encryption, an authentication token or user-verification phrase, protect you from would-be
hackers. Others, like choosing an obscure personal security question and answer, help us confirm your
identity you when you've forgotten your account password.
Some simple security measures can go a long way. For example, changing your account password frequently and
closing down your browser window when finished are excellent ways of minimizing your security exposure. Here's a
quick summary of the thinkorswim security system:
- 128-bit SSL encryption: All personal data transactions on the our website are handled with

- User Verification Phrase: All clients are given a "user verification phrase" when they
register. This phrase can only be retrieved by a genuine thinkorswim representative. Anytime someone
asks you for your thinkorswim account information you can ask them for your user verification
phrase. Only a legitimate thinkorswim representative will know what you are talking about and we like
it that way...learn more >
- Personal Security Question & Answer: Should you forget your password we can quickly and
easily confirm your identity using your personal security question and answer.
