If you change your password or log in from a different device, we will provide you with a one-time identification code to verify your identity. This one-time identification code is one of a number of security measures American Express National Bank uses to protect the security of your account.
We send the one-time identification code to you by email, SMS (Text) message, or phone call to ensure we are communicating with the authorized account holder. For phone, the one-time identification code can only be sent to direct lines. If you select this option, and your phone number requires dialing an extension, you will not receive your one-time identification code. For email, some internet service providers and corporate email servers may block these messages. Consequently, they are located in a “junk” folder or are not delivered at all. Text message is usually the fastest and most reliable delivery method.
Please note that while we try to send the code immediately, many factors may delay when you receive the code in your inbox or mobile device.
