A transaction password is a password used to approve transactions such as transfers. It is a unique number assigned to the account holder. When filling out an application for the first time, entering a transaction password allows you to save a non-submitted application. In the case of creating a wallet, a transaction password is prompted to be set, which is used to make transactions. The transaction password is separate from the login password, which is used to access the account. To make payments securely on the Bank One Mobile Banking app, a transaction password needs to be set. If you forget or need to reset your transaction password, there are ways to generate or reset it, such as through Connect Online.
