Only the signers on an account, using their Citibank ATM Card / Credit Card number and PIN, will be able to access the account. It's important to remember that your ATM Card is valuable and that you exercise care with it. Never lend your card to anyone and never accept advice from strangers while you are using it. Also, be sure to keep your PIN to yourself. This code is an important means of protection for you. Never write it down anywhere.

Encryption technology helps provide secure transmission of information along the Internet by encoding the transmitted data using a mathematical formula to scramble the data. Without a corresponding "decoder," the transmission would look like jumbled text and would be unusable.
Encryption technology can be used for a host of applications, including electronic commerce (sending credit card numbers for orders or transmitting account information), e-mail messages and sensitive documents.
Basic encryption involves the transmission of data from one party to another. The sender encodes the data by scrambling it, and then sends it on. The receiver must decode the data with the correct "decoder" in order to read and use it.
The effectiveness (or level of security) for encryption is measured in terms of how long the key is -- the longer the key, the longer it would take for someone without the correct "decoder" to break the code. This is measured in bits (e.g., 40-bit encryption, the level of encryption used with many browsers, versus 128-bit encryption, the level of encryption required to use Citibank Online).128 bit-encrypted messages are over 309,485,000,000,000,000,000,000,000 times harder to break than 40-bit messages.
All financial transactions are secured using 128-bit encryption, which is currently the strongest available for commercial use. In case your browser supports a lower level of encryption we suggest you upgrade your browser.
Citibank currently offers 3 levels of security to help safeguard your financial information :
Strong Encryption (128-bit) :
All data sent to and from Citibank is "scrambled" and "reassembled" between Citibank and your personal computer to protect your personal and financial information. 128-bit encryption, the highest level of encryption commercially available, means there are 2128 possible combinations of "keys" but only one that will "unlock" the information.
Personal Identification Number (PIN) :
Your PIN must be entered every time you sign on to Citibank Online. Remember; always keep your PIN confidential.
Automatic Time Out :
When there is no activity for 6 minutes, Citibank will terminate your secure Citibank Online session to help protect against unauthorized access.
Digital Certificates provide the user with third Party (Certification Authority) evidence of the server's authenticity. This safeguards users from trusting unauthorized sites and allows the session to be encrypted. The customer will see a "closed lock" icon on the leftmost (Netscape) / rightmost (Internet Explorer) bottom corner of the Citibank Online Screen. Clicking on the image of lock or a key at the bottom of the browser window when you have reached the page that needs your ATM Card / Credit Card number and PIN input will allow the customer to see the VeriSign Certificate authenticating the site.
