Learn how to become a more discerning computer user no matter where you are.
Update Your Security Preferences
Make your User ID and Password as secure as possible
A good password is paramount to your security. Avoid using a password or a variation of a password that you already use on another website. Also, avoid using any variation of your name, or names of family members or pets, as these can sometimes be found on social media. Focus on length and complexity. Adding a "1" or a "!" to the end, or substituting "$" for "S" are combinations that are easily hacked — increase complexity to better protect yourself.
Nickname Your Accounts
Nicknaming an account makes it easier to identify online and at ATMs — and it conceals your full account number.
Tips for Safe Computer Use
Use a personal firewall
Many internet service providers offer this feature. A personal firewall protects your home computer against unauthorized access. It is designed to protect only the computer on which it is installed. It protects you by controlling the traffic that comes in and goes out from your computer. It watches for attempts to access your system and blocks communications to and from sources you don't permit.
Beware of malware infection with drive-by download
Drive-by downloads may happen when visiting a malicious or vulnerable website, viewing an e-mail message or by clicking on a deceptive pop-uppop up window. Malware is malicious software installed on your computer which has a harmful intent that can, for example, capture your login passwords and other personal data. Examples of malware include software such as spyware, adware, viruses, etc. The best way to protect yourself from malware is to exercise caution before installing programs on your computer or opening email attachments. Here are some precautions that are important to take:
Only install applications and software from well-known companies you trust.
Make sure your computer is cleansed from viruses/spyware and has up-to-date anti-virus and anti-spyware software installed.
Keep your operating system and browser up-to-date with the latest security updates and patches.
Install anti-virus, anti-spyware and malware detection software
The best defense against computer attacks is preventative software. You will need to update the software regularly to guard against new risks, so download updates from your provider as soon as they're available. Or better yet, set the software to update automatically.
Use a pop-uppop up blocker
Set your browser preferences to block pop-upspop ups — aside from being annoying, these pop-upspop ups can contain inappropriate content or have malicious intentions.
Go directly there
The best way to get to any site is to type its address (URL) into your browser and then bookmark it.
Tips for Public Network or Computer Use
Only use wireless networks you trust
Networks in internet cafés, hotels, and libraries are usually not secure and are easy to tamper with. Even if they provide you with a password, that does not guarantee a secure connection. You should avoid using any public computers for online banking.
Avoid using a public or shared computer for personal transactions
Anyone who uses the computer after you and visits the same websites may be able to sign on to your accounts. To address this issue, after you sign off, select the option to "Remove a user", if that option is available. Also, make sure to clear the internet history and any cookies stored.
Banking from your mobile device
When you use Citi Mobile® App for your everyday banking, you're protected with the same technology that is provided with Citi Online. Enroll in fingerprint or facial recognition to sign into your Citi Mobile® App for fast, convenient access. If we see any suspicious login attempts we'll use additional authentication methods such as password or security questions to further protect your information.
Safely Download the Citi Mobile® App
When downloading the Citi Mobile® App to your mobile device, be sure to go to a trusted source such as the App Store on the iPhone® and iPod Touch®, or Google Play™ on your Android™ device, rather than a third-party source.
Before you download the Citi Mobile® App, we recommend that you go to citi.com/mobileapp on your mobile device for instructions.
Also, look at the developer of any apps you download. Citi will not direct you to download apps that are not developed by Citi.
Ways to Keep Your Information Safe
Download anti-malware protection for your phone, tablet, e-reader or any other device that has mobile access to the internet. This software should be able to scan the device, identify and remove malware, plus check applications for malware before downloading from application stores.
Do not root or jailbreak your mobile device to get around limitations set by your carrier or device manufacturer. It will remove any protections built into the device to defend against mobile threats.
Beware of everything you download onto your smartphone, especially applications. Only use reputable application markets. Look at the developer's name, check out reviews and star ratings. Always check the permissions an application requests and ensure that the permissions the application requests match the features the application provides.
For extra protection, most mobile devices offer a screen lock or other security settings you can enact to help ensure only you have access to your device.
If your phone is stolen or lost, the first thing you should do is call your wireless carrier (or visit their website) to report the incident. Next, contact your Citibank Customer Service agent and report the case. We also recommend that you change your User ID and Password for your online access to Citi as well as any other accounts you access from your mobile phone.
Ensuring QRq r Codes are Valid
Quick Response (QRq r) codes can direct your mobile device to a malicious site. If you receive a QRq r code via email, be cautious and follow the tips below to help you identify the email as being sent by Citi.
Look for the last 4 digits of your card number or the last 4 digits of your specified bank account number. Also, check the sender, header and footer details carefully to help confirm it is a valid Citi email.
QRq r codes that are not from Citi may direct your mobile device to a malicious site so proceed with caution if you receive one.
