Digital financial management with account balance preview by paired user-authorized second client device without user authentication

A computer program product comprising at least one non-transitory computer readable medium having with a set of instructions of computer-executable program code, which when executed by one or more processors of a computing device, cause the computing device to:

• detect execution of a mobile application associated with a financial institution on a first client device of a user having one or more financial accounts at the financial institution;
• analyze proximity data between the first client device and a user-authorized second client device;
• determine, responsive to the analysis, that a spatial proximity between the first client device and a user-authorized second client device is within a threshold proximity;
• detect, responsive to the detection of the execution of the mobile application having the spatial proximity between the first client device and the user-authorized second client device within the threshold proximity, a pairing between the first client device and the user-authorized second client device;
• and
• cause, based on the detection of the pairing, display of a graphical user interface on a user interface of the user-authorized second client device to visually display one or more account balances associated with the one or more financial accounts.

A computer-implemented method, comprising:

• detecting, by one or more financial institution servers associated with a financial institution, execution of a mobile application associated with a financial institution on a first client device of a user having one or more financial accounts at the financial institution;
• analyzing proximity data between the first client device and a user-authorized second client device;
• determining, responsive to the analysis, that a spatial proximity between the first client device and a user-authorized second client device is within a threshold proximity;
• detecting, by the one or more financial institution servers in response to the detection of the execution of the mobile application having the spatial proximity between the first client device and the user-authorized second client device within the threshold proximity, a pairing between the first client device and the user-authorized second client device;
• and
• causing, by the one or more financial institution servers based on the detection of the pairing, display of a graphical user interface on a user interface of the user-authorized second client device to visually display one or more account balances associated with the one or more financial accounts.
