Sign up for TCU eStatements

At TCU you can receive eStatements online through TCU Internet Banking. Your account statements will no longer have to sit in your mailbox waiting for you to pick them up! eStatements are safe and secure. To register for eStatements, log in to Internet Banking and click on "eStatements". Once you register for eStatements, you will no longer receive paper statements. Contact a TCU Representative for more details.

Call (800) 552-4745 for more information or to answer any questions or concerns.


Access to Internet Banking requires your member number and a unique password. This information along with any interactions and\or transactions performed is encrypted during transmission. You cannot use any part of your member number or Social Security Number as your password. TCU strongly encourages you to define a unique password that only you can provide and is not tied to any personally identifiable information that a hacker could obtain from a phone book or the Internet.

Enhanced Login Security

TCU provides Enhanced Login Security which significantly increases your level of protection online. Not only will your password and user id be recognized, but your device will be recognized as well. If we don't recognize your device – you've logged in from a public computer or one you haven't used before - you will be prompted to provide a secure access code which will be sent to you. This step acts as an additional line of defense against unauthorized access to your accounts.

Timed log-off

The TCU Internet Banking platform will log you off after 10 minutes of inactivity. This will reduce the risk of someone else accessing your financial information if you leave your PC unattended.


Internet Banking systems are protected 24 hours a day by a variety of security measures, to include firewalls that block unauthorized entry.


Throughout your Internet Banking session, from login, to transaction activity, to log-off, all interactions are encrypted between your browser and the web server. TCU employs some of the strongest levels of encryption available today.

You can identify a secure (encrypted session) by looking for the "closed lock" icon in the lower right-hand corner (Microsoft Internet Explorer) or in the right end of the address bar (Firefox 2) or in the top right corner (Safari) of your browser. Additionally, the Web address or URL will begin with https://.... This indicates the page you are viewing uses encryption. The "s" stands for "secured."

More Security Measures

While the measures noted above are instrumental to your safe interaction with Internet Banking, continuous monitoring is in place to alert TCU of any unusual activity. If suspicious activity is identified, TCU will take necessary steps to shut down access until the issue has been resolved. Security of your information is a top priority and we take it very seriously.

Debit Card Fraud Alerts

TCU has enlisted the assistance of our Debit/ATM Card process, Star Systems, to identify potentially fraudulent transactions and then contact you to verify whether they were authorized or not. Calls will originate from (800) 327-8622 and you will be asked your name, the phone number the message was left on if applicable, along with information about the transaction(s) in question.

It's not always easy to identify online fraud. Understanding how fraudulent activity takes place helps with prevention, and keeps you safe.

Safeguard your email

Email is often a vehicle used to transmit malware and commit fraud. It is important to evaluate your email behaviors and develop good habits to help protect your computer and your identity.

In addition to viruses and worms that can be transmitted via email, phishing also threatens email users. A type of email fraud, phishing occurs when a perpetrator, posing as a legitimate, trustworthy business, attempts to acquire sensitive information like passwords or financial information.

How to safeguard your email:

1) Never open or respond to SPAM (unsolicited bulk email messages).

Delete all spam without opening it. Responding to spam only confirms your email address to the spammer, which can actually intensify the problem.

2) Never click on links within an email.

It's safer to retype the Web address than to click on it from within the body of the email.

Don't open attachments from strangers.

If you do not know the sender or are not expecting the attachment, delete it.

3) Don't open attachments with odd filename extensions.

Most computer files use filename extensions such as ".doc" for documents or ".jpg" for images. If a file has a double extension, like "heythere.doc.pif," it is highly likely that this is a dangerous file and should never be opened. In addition, do not open email attachments that have file endings of .exe, .pif, or .vbs. These are filename extensions for executable files and could be dangerous if opened.

4) Never give out your email address or other sensitive or personal information to unknown web sites.

If you don't know the reputation of a Web site, don't assume you can trust it. Many Web sites sell email addresses or may be careless with your personal information. Be wary of providing any information that can be used by others for fraudulent purposes.

5) Never provide sensitive information in email.

Forged email purporting to be from your financial institution or favorite online store is a popular trick used by criminals to extract personal information for fraud.

6) Don't believe the hype.

Many fraudulent emails send out urgent messages that claim your account will be closed if sensitive information isn't immediately provided, or that important security needs to be updated online. Your financial institution will never use this method to alert you of an account problem.

7) Be aware of poor design, bad grammar and spelling.

A tell-tale sign of a fraudulent email or Web site includes typos and grammar errors as well as unprofessional design layout and quality. Delete them immediately.

8) Backup your sensitive data records.

Consider backing up all sensitive files. This will not only help you restore damaged or corrupted data, but it will help protect against fraud attacks and help recover lost files if needed.

9) Safeguard your identity online.

In addition to protecting your email, there are a number of guidelines to follow that will help safeguard your identity online.

10) Do not allow a website to keep sensitive information or credentials for future convenience.

It is a common practice when registering for access to a Web site or making a purchase from a Web site to be asked if you want to keep your access credentials, credit card number or other sensitive information on file as a matter of convenience. This common request is referred to as "remembering" for the future use.

11) Be selective about where you surf.

Not all Web sites are benign. Sites that are engaged in illegal or questionable activities often host damaging software and make users susceptible to aggressive computer attacks.

12) Don't choose "Remember My Password."

You should never use the "remember password" feature for online banking or transactional Web sites.

13) Don't use public computers for sensitive operations.

Since you cannot validate the computer's integrity, there's a higher risk of fraud when you log in from a public computer.

14) Work on a computer you trust.

Firewalls, antivirus, anti-spyware and other protection devices help keep a computer properly monitored and provide peace of mind. These tools are important in order to protect your computer and data. A good firewall is critical if you commonly access the Internet via a wireless connection. It is also important to keep your computer up-to-date with patches to security tools as well as to the operating system and other programs on your computer. Make sure to configure your computer to update all security fixes.

15) Select a strong password.

The best password is an undetectable one. Never use birth dates, first names, pet names, addresses, phone numbers or Social Security Numbers. Use a combination of letters, numbers and symbols. Be sure to change your passwords regularly.

16) Use a secure browser.

Only use secure Web pages when you're conducting transactions online (a Web page is secure if there is a locked padlock in the lower left-hand corner of your browser).

17) Sign off, shut down, disconnect.

Always sign off or logout from your Internet Banking session or any other Web site that you've logged into using a user ID and password. When a computer is not in use, it should be shut down or disconnected from the Internet.

18) Lock your computer when it is not in use.

This helps protect you from unauthorized user access.

19) Beware of shoulder surfing.

This is a common tactic that happens in public places such as coffee shops, airports and libraries etc. where an attacker will look over your shoulder when you're logged in to obtain your sensitive information. Be vigilant and aware of prying eyes.

20) Set up a timeout.

The timeout feature is an additional safety check. It can prevent others from continuing your online banking session if you left your PC unattended without logging out. You can set the Timeout period in the User Options screen.

Tactics that fraudsters employ all share the same goal: to obtain your personal, confidential and financial information for fraudulent use.

From obtaining your information 'the old fashioned way' via discarded mail, to emails that ask you to verify personal information under the guise of a trusted source – like TCU – fraudulent activity comes in many different forms.

Fraud tactics include:

Dumpster Diving: Thieves rummage through trash looking for bills or other paper that includes your personal information.

Malware: Also known as 'malicious software', malware is designed to harm, attack or take unauthorized control over a computer system. Malware includes viruses, worms and Trojans. It's important to know that Malware can include a combination of all three of the types noted.

Phishing: A scam that involves the use of replicas of existing Web pages to try to deceive you into entering personal, financial or password data. Often suspects use urgency or scare tactics, such as threats to close accounts.

Vishing: Vishing is a type of phishing attack where the attacker uses a local phone number in the fake email as a means of obtaining your sensitive information. The goal is to fool you into believing the email is legitimate by instructing you that responding to the request by phone is safer than responding by email and shows authenticity. The unsuspecting caller is then tricked through an automated phone system to relinquish their sensitive information.

Pharming: Pharming takes place when you type in a valid Web address and you are illegally redirected to a Web site that is not legitimate. These 'fake' Web sites ask for personal information such as credit card numbers, bank account information, Social Security numbers and other sensitive information.

Trojan: A Trojan is malicious code that is disguised or hidden within another program that appears to be safe (as in the myth of the Trojan horse). When the program is executed, the Trojan allows attackers to gain unauthorized access to the computer in order to steal information and cause harm. Trojans commonly spread through email attachments and Internet downloads. A common Trojan component is a "keystroke logger" which captures a user's keystrokes in an attempt to capture the user's credentials. It will then send those credentials to the attacker.

Spoofing: Spoofing is when an attacker masquerades as someone else by providing false data. Phishing has become the most common form of Web page spoofing. Another form of spoofing is URL spoofing. This happens when an attacker exploits bugs in your Web browser in order to display incorrect URLs in your browser location bar. Another form of spoofing is called "man-in-the-middle". This occurs when an attacker compromises the communication between you and another party on the Internet. Many firewalls can be updated or configured to significantly prevent this type of attack.

Spyware: Loaded on to your computer unbeknownst to you, spyware is a type of program that watches what users do and forwards information to someone else. It is most often installed when you download free software on the Internet. Unfortunately hackers discovered this to be an effective means of sending sensitive information over the Internet. Moreover, they discovered that many free applications that use spyware for marketing purposes could be found on your machine, and attackers often use this existing spyware for their malicious means.

Pop-Ups: A form of Web advertising that appears as a "pop-up" on a computer screen, pop-ups are intended to increase Web traffic or capture email addresses. However, sometimes pop-up ads are designed with malicious intent like when they appear as a request for personal information from a financial institution, for example.

Virus: A computer virus is a malicious program that attaches itself to and infects other software applications and files without the user's knowledge, disrupting computer operations. Viruses can carry what is known as a "payload," executable scripts designed to damage, delete or steal information from a computer.

A virus is a self-replicating program, meaning it copies itself. Typically, a virus only infects a computer and begins replicating when the user executes the program or opens an "infected" file.

Viruses spread from computer to computer only when users unknowingly share "infected" files. For example, viruses are commonly spread when users send emails with infected documents attached.

RetroVirus: This virus specifically targets your computer defenses. It will look for vulnerabilities within your computer operating system or any third party security software. Most security vendors have some form of tamper-proof measure in place, so it is important to keep your patches up-to-date. Retro Viruses are usually combined with another form of attack.

Worm: A worm is similar to a virus but with an added, dangerous element. Like a virus, a worm can make copies of itself; however, a worm does not need to attach itself to other programs and it does not require a person to send it along to other computers.

Worms are powerful malware programs because they cannot only copy themselves; they can also execute and spread themselves rapidly across a network without any help.
