Financial account authentication

A computer-implemented method, comprising:

• receiving, from a user device, a request to include user data describing a user account in an interface, the user account being associated with an account provider;
• identifying one or more metadata attributes for accessing the user account associated with the account provider;
• receiving a public digital key associated with the account provider;
• transmitting, to the user device, data describing the one or more metadata attributes and the public digital key associated with the account provider;
• receiving, from the user device, respective values for the one or more metadata attributes, the respective values having been encrypted by the user device using the public digital key;
• storing the encrypted values for the one or more metadata attributes for use in accessing and aggregating the user data describing the user account;
• transmitting, to a computer system of the account provider, the encrypted values for the one or more metadata attributes for logging in into one or more webpages associated with the account provider;
• generating for display in the interface the user data describing the user account;
• determining that the public digital key associated with the account provider has expired;
• and
• based on determining that the public digital key associated with the account provider has expired, deleting the stored encrypted values for the one or more metadata attributes.

A non-transitory computer storage medium encoded with a computer program, the computer program comprising instructions that when executed by a data processing apparatus cause the data processing apparatus to perform operations comprising:

• receiving, from a user device, a request to include user data describing a user account in an interface, the user account being associated with an account provider;
• identifying one or more metadata attributes for accessing the user account associated with the account provider;
• receiving a public digital key associated with the account provider;
• transmitting, to a user device, data describing the one or more metadata attributes and the public digital key associated with the account provider;
• receiving, from the user device, respective values for the one or more metadata attributes, the respective values having been encrypted by the user device using the public digital key;
• storing the encrypted values for the one or more metadata attributes for use in accessing and aggregating the user data describing the user account;
• transmitting, to a computer system of the account provider, the encrypted values for the one or more metadata attributes for logging in into one or more webpages associated with the account provider;
• generating for display in the interface the user data describing the user account;
• determining that the public digital key associated with the account provider has expired;
• and
• based on determining that the public digital key associated with the account provider has expired, deleting the stored encrypted values for the one or more metadata attributes.

A system comprising electronic circuitry configured to perform operations comprising:

• receiving, from a user device, a request to include user data describing a user account in an interface, the user account being associated with an account provider;
• identifying one or more metadata attributes for accessing the user account associated with the account provider;
• receiving a public digital key associated with the account provider;
• transmitting, to a user device, data describing the one or more metadata attributes and the public digital key associated with the account provider;
• receiving, from the user device, respective values for the one or more metadata attributes, the respective values having been encrypted by the user device using the public digital key;
• storing the encrypted values for the one or more metadata attributes for use in accessing and aggregating the user data describing the user account;
• transmitting, to a computer system of the account provider, the encrypted values for the one or more metadata attributes for logging in into one or more webpages associated with the account provider;
• generating for display in the interface the user data describing the user account;
• determining that the public digital key associated with the account provider has expired;
• and
• based on determining that the public digital key associated with the account provider has expired, deleting the stored encrypted values for the one or more metadata attributes.
