We are committed to security and fraud prevention by providing you with secure access to online accounts and protecting your personal financial information from fraud. We take security and fraud protection seriously.

Chelsea Groton Bank will never contact you to ask for your online/mobile banking User ID and Password, or Debit Card number. If you receive any notification or phone call requesting this information, do not provide this or any other personal information. When in doubt, or if you feel your information may have been compromised, contact our Customer Care Center at 860-448-4200 during business hours.

If your personal online information was compromised, change your User ID, Password, and Security questions immediately in our Online and Mobile Banking app. It’s important to only make account updates on a device you know is secure. Please email Security@chelseagroton.com at any time, or notify a Chelsea Groton Bank representative during regular business hours by calling our Customer Care Center at 860-448-4200.

Take proactive measures to protect your online identity! Here are additional tips for security and fraud prevention:

  • Never share your User ID and Password with anyone. It’s a best practice for joint account holders to have separate login IDs and passwords.
  • Use caution when conducting business online. Do you know who you’re online with? Is it a known business or known individual? Were you expecting communication from them or was it unsolicited?
  • Use caution when opening attachments or links provided in an email. If you hover over a link without clicking it, you’ll notice the full URL of the link’s destination. Do you recognize the website? If not, do not open.
  • Never send money, gift cards, or cash a check or transfer money via a wire or electronic payment system. If you’re being threatened with law enforcement action, or you think it sounds ‘too good to be true’, it’s likely a scam. 
  • Imposter scams are going around. Scammers may claim to be from your bank, say there is fraud on your account, and instruct you to transfer money to stop it.
    • If this happens to you: Do not provide any personal information or transfer money as a result of unsolicited calls, texts, emails or pop-ups. Chelsea Groton Bank will never reach out and ask you to transfer money for any reason. If you are ever unsure, hang up the phone and call Chelsea Groton’s Customer Care team at 860-448-4200 or email Security@chelseagroton.com
  • There is a current scam technique called phishing, where scammers are attempting to deceptively steal money or personal information. It will seem like it’s coming from a legitimate trusted source and will require your immediate action.
    • If this happens to you: Don’t feel pressure to respond immediately. Do not click on links or attachments as they may contain malware. Do not provide any financial or personal information to the caller. Chelsea Groton Bank will never reach out to you to ask for account details.
