What is a One-Time Passcode?

A One-Time Passcode is an added security feature for Online and Mobile Banking. If we detect unusual or suspicious activity at sign on, a unique passcode will be sent to your verified mobile number or email address that once entered will grant you access to your account.

Help us protect your account by ensuring we have your correct email address and verified phone number.

To avoid being asked for a passcode allow SunTrust to know your location.
