Processing authentication requests to secured information systems using machine-learned user-account behavior profiles

A method, comprising:

• at a computing platform comprising at least one processor, a communication interface, and memory:
• receiving, by the at least one processor, via the communication interface, from an account portal computing platform, a first authentication request corresponding to a request for a first user of a first client computing device to access one or more secured information resources associated with a first user account in a first client portal session;
• based on receiving the first authentication request from the account portal computing platform, capturing, by the at least one processor, one or more behavioral parameters associated with the first client computing device;
• authenticating, by the at least one processor, the first user of the first client computing device to the first user account based on the one or more behavioral parameters associated with the first client computing device and one or more authentication credentials associated with the first authentication request;
• based on authenticating the first user of the first client computing device to the first user account, generating, by the at least one processor, one or more authentication commands directing the account portal computing platform to allow access to the one or more secured information resources associated with the first user account in the first client portal session;
• sending, by the at least one processor, via the communication interface, to the account portal computing platform, the one or more authentication commands directing the account portal computing platform to allow access to the one or more secured information resources associated with the first user account in the first client portal session;
• after sending the one or more authentication commands directing the account portal computing platform to allow access to the one or more secured information resources associated with the first user account in the first client portal session, capturing, by the at least one processor, first activity data associated with one or more interactions in the first client portal session;
• and
• updating, by the at least one processor, a first behavioral profile associated with the first user account based on the first activity data associated with the one or more interactions in the first client portal session.

One or more non-transitory computer-readable media storing instructions that, when executed by a computing platform comprising at least one processor, a communication interface, and memory, cause the computing platform to:

• receive, via the communication interface, from an account portal computing platform, a first authentication request corresponding to a request for a first user of a first client computing device to access one or more secured information resources associated with a first user account in a first client portal session;
• based on receiving the first authentication request from the account portal computing platform, capture one or more behavioral parameters associated with the first client computing device;
• authenticate the first user of the first client computing device to the first user account based on the one or more behavioral parameters associated with the first client computing device and one or more authentication credentials associated with the first authentication request;
• based on authenticating the first user of the first client computing device to the first user account, generate one or more authentication commands directing the account portal computing platform to allow access to the one or more secured information resources associated with the first user account in the first client portal session;
• send, via the communication interface, to the account portal computing platform, the one or more authentication commands directing the account portal computing platform to allow access to the one or more secured information resources associated with the first user account in the first client portal session;
• after sending the one or more authentication commands directing the account portal computing platform to allow access to the one or more secured information resources associated with the first user account in the first client portal session, capture first activity data associated with one or more interactions in the first client portal session;
• and
• update a first behavioral profile associated with the first user account based on the first activity data associated with the one or more interactions in the first client portal session.
