Unified identity verification

A method, comprising:

• generating, by a computing system, an authentication token for an electronic account based on verifying a set of security credentials for the electronic account;
• determining, by the computing system, a time interval over which the authentication token is valid;
• storing, by the computing system, user permission information that specifies a set of information for the electronic account that the computing system is authorized to share with one or more selected entities;
• providing, by the computing system, the authentication token to a client device;
• receiving, by the computing system from a requesting computing system, an authentication request that includes the authentication token;
• in response to the authentication request, the computing system:
• verifying the authentication token and that the authentication request was received during the time interval;
• sending, to the requesting computing system based on the verifying, an authentication confirmation for the electronic account, wherein the authentication confirmation allows the requesting computing system to authenticate a request from the client device without receiving the set of security credentials;
• and
• sending, to the requesting computing system based on determining that the requesting computing system is associated with one of the one or more selected entities, at least a portion of the set of information.

A system, comprising:

• one or more processors;
• and
• one or more memories having program instructions stored thereon that are executable by the one or more processors to:
• generate an authentication token for an electronic account based on verifying a set of security credentials for the electronic account;
• determine a time interval over which the authentication token is valid;
• store user permission information that specifies a set of information for the electronic account that the system is authorized to share;
• provide the authentication token to a client device;
• receive, from a requesting computing system, an authentication request that includes the authentication token;
• in response to the authentication request:
• verify the authentication token and that the authentication request was received during the time interval;
• send, to the requesting computing system based on the verification, an authentication confirmation for the electronic account, wherein the authentication confirmation is usable by the requesting computing system for authentication of a request from the client device without receiving the set of security credentials;
• and
• send, to the requesting computing system, at least a portion of the set of information.

A non-transitory computer-readable medium having instructions stored thereon that are executable by a computing system to perform operations comprising:

• generating an authentication token for an electronic account based on verifying a set of security credentials for the electronic account;
• storing user permission information that specifies a set of information for the electronic account that the computing system is authorized to share with one or more selected entities;
• providing the authentication token to a client device;
• receiving, from a requesting computing system, an authentication request that includes the authentication token;
• in response to the authentication request:
• verifying the authentication token;
• sending, to the requesting computing system based on the verifying, an authentication confirmation for the electronic account, wherein, due to the authentication confirmation, the requesting computing system does not receive the set of security credentials for the electronic account;
• and
• sending, to the requesting computing system based on determining that the requesting computing system is associated with one of the one or more selected entities, at least a portion of the set of information.
