Common Questions

  • Are there password requirements for my OnLine Banking account?

    Password must contain at least 8 and no more than 32 characters, both upper and lower case letters and at least one number. As a security precaution, avoid using previous passwords. When changing your password, there must be information in all three boxes. You must complete the following: your current password, new password, and confirm new password boxes. If you forgot your password, please utilize the “Forgot Your Password” link to change your password. 

  • What do I do if my OnLine Banking account is locked out?

    If you have disabled your account because you have answered the security questions or your password incorrectly too many times, please contact our member service department at 800-645-4728 Monday through Wednesday 8:30am – 5:00pm; Thursday 8:30am – 6:00pm; Friday 8:30am – 5:00pm; and, Saturday 8:30am – 12:00pm. They will be able to provide you with a temporary pass code that will allow you to login. 

  • What types of transactions can I conduct through Mobile Banking?

    Mobile Banking can be used for balance inquiries, to transfer funds that you are an authorized signer, check your account history, view loans and make payments, create and pay bills, and deposit checks. In addition to conducting transactions, you can also review our branch and ATM locations and connect via phone to a GSCU Member Service Rep and deposit checks. 

  • What is Mobile Deposit?

    Mobile Deposit allows members to deposit checks utilizing their smartphone or tablet devices. You can deposit money in all of your GSCU share accounts.
