Store API tokens as SHA-256 hashes instead of plaintext and return the token value only in the create response. List no longer exposes the token, and the UI drops the Show/Copy buttons in favor of a one-time reveal modal at creation. Match hashes the presented bearer token before the constant-time compare, and a migration hashes any pre-existing plaintext rows in place so existing tokens keep authenticating. Docs and translations updated.
