Secure Email

TFCU provides a secure method of exchanging sensitive information through email via the Cisco Registered Envelope Service (CRES). Prior to viewing or sending a secure message, you will be required to create a Password associated with your email account. Please see below for full details.

Frequently Asked Questions

I don’t have an account with CRES. How do I sign up?

If the Register button is not displayed, leave the password field empty, and click the Open button to begin the registration process. For more information about opening a Registered Envelope for the first time, see the Help Guide.

Can I send attachments using CRES?

Attachments can be sent by either replying to a received secure message (from within the CRES envelope) or by initiating a secure message.
