Systems and methods for processing financial transactions using compromised accounts

A computer-implemented method comprising:

• receiving, from a device, a financial transaction comprising an account number associated with a financial account;
• based on a determination that the account number is suspended, determining whether authorization data associated with the financial account exists to authorize financial transactions associated with the account number after the account number is suspended;
• based on a determination that the authorization data exists, determining a first temporary identifier;
• receiving a second temporary identifier from the device;
• and
• based on a determination that the first temporary identifier is the same as the second temporary identifier, approving the financial transaction.

A computer-implemented method comprising:

• receiving, from a device, a notification indicating that an account number of a financial account is suspended;
• receiving, from the device, a request for authorization data authorizing financial transactions associated with the account number after the account number is suspended;
• based on user input, generating the authorization data;
• and
• transmitting the authorization data to the device.
