This extension provides means for keeping track of multiple identifiers of different configurable types for *Contact* entities by adding a multi-value custom field group and an API for easily identifying contacts by those ID records. Warning **Incompatible with CiviCRM Core `5.71` prior to version `1.4`** The extension is incompatible with CiviCRM Core starting from version `5.71.0`due to misuse of the API internally (which actually worked by accident). *Identity Tracker* version `1.4` fixes this incompatibility. ### Health Score 45 — FairBetter than 91% of packages Maintenance79 Regular maintenance activity Popularity27 Limited adoption so far Community21 Small or concentrated contributor base Maturity46 Maturing project, gaining track record Bus Factor2 2 contributors hold 50%+ of commits How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
