Admin API keys are moving to the Harness platform's Service Account capability. There, you can sort by Newest/Oldest, Name (A->Z), Name (Z->A), Email (owner) (A->Z), and Email (owner) (Z->A).

If this request is focused on SDK API Keys (and I suspect it might be), then we'll need to look into our options here. Note that once migrated to Harness, SDK Keys are listed under each project rather than across projects, which will act as an initial filter to reduce the number of keys, but if you have hundreds, it's likely you'll still have considerably more than a page of them per project, so we will need to evaluate solutions for this.
