1. A computing platform, comprising:
at least one processor;
a communication interface communicatively coupled to the at least one processor; and
memory storing computer-readable instructions that, when executed by the at least one processor, cause the computing platform to:
process a first set of login events associated with a first user account;
build a first user-specific authentication model for the first user account based on first activity data captured during the first set of login events associated with the first user account;
process a second set of login events associated with a second user account;

identify one or more activity parameters associated with at least one authentication model for refinement;
generate one or more activity prompts based on the one or more activity parameters associated with the at least one authentication model identified for refinement; and
