Internet Security

What we do to protect you

Our digital banking system has industry-leading security capabilities, including robust fraud prevention, cyber security features and high-risk transaction protections to ensure that your transactions are secure while data is transmitted between your device and our banking server.


We use 256-bit TLS encryption on our desktop website and mobile app, enabling you to easily and securely complete banking transactions on your phone, tablet or computer.

Controlled account access

You have complete control over your account access and only you know your sign-in credentials, username and password. Our employees do not have this information, nor do they require it from you. Never share your account information with anyone. 

Password protections

To prevent unauthorized access, repeated failed attempts to login to your account will result in access being disabled. To unlock your account you must contact Memberline.

One Time Passcodes

Certain activities related to online banking will require extra verification through one-time passcodes. Please ensure that your mobile phone and email are up to date with TCU FInancial Group to ensure best functionality of this safety feature. 

Protecting yourself

Online security is a joint responsibility between TCU Financial Group and our members. We need to work together to keep you safe. Observing basic security measures can greatly enhance your convenience and online safety. 

  • Do not provide account or personal details in email, the message center in online banking provides a secure and confidential way to communicate with us online.
  •  Know what is happening in your account, setup alerts within online banking to notify you about large account transactions.  It is a great way to be made aware of any suspicious or unauthorized activity.
  • Do not follow links from emails to your financial institution’s website. Type in the address or use a bookmark you know to be accurate.
  • Be wary of messages designed to pressure you in to action…”your account has been closed”, “our security department has locked your account”

Practice proper password management

  • Use strong, unique passwords, avoid re-using passwords from other sites and services you use. 
  • Choose a password that is memorable for you, but not easy to guess, and avoid using personal information like phone numbers, birth dates, your pet’s name, etc. 
  • Don’t use the auto-save function for user names and passwords on your browser/device. Consider using protected password management software or another secure system for storing passwords.
  • Never share your password with anyone, no TCU staff will ever ask you to share your password or personal verification questions and answers.
  • Be sure to sign out and close your browser at the end of each session.
