You can sleep easy with Citibank Online, with its three levels of security helping to safeguard your financial information.
All data sent to and from Citibank is "scrambled" and "re-assembled" between Citibank and your personal computer to protect your personal and financial information. The highest level of encryption generally available today (128-bit) means there are two to the power of 128 possible combinations of "keys", but only one that will "unlock" the information.
A password is required every time you log on to Citibank Online. Always keep it confidential and change passwords that may have been compromised. Citibank staff will also never ask for your Citibank Online user ID and password.
Citibank will terminate your secure Citibank Online session after 15 minutes of inactivity. This prevents the unauthorized use of your session by anyone else.
