SharePoint Claims (Login Name) Decoder

Paste a SharePoint claims login name, the i:0#.f|membership|… and c:0t.c|tenant|… strings you see in permission reports, PnP output and ULS logs. This turns it into a plain-English identity and explains every part.

The claim you paste is never sent anywhere. All the decoding happens in your browser.
