How can I log in to my American Express Serve prepaid card account?

To log into an American Express Serve prepaid card account, one must navigate to the Serve website or open the Serve mobile app. Once there, locate the login section and enter the username and password associated with the Serve account. If it's one's first time logging in or if they have not yet registered their card, they would need to go through the registration process by clicking on "Register Your Card" and following the prompts to set up their online account access. If they encounter any issues or forget their login credentials, it is recommended to click on the "Forgot Username or Password?" link for assistance or contact American Express Serve customer support for further help and guidance on account access.
