Before using this template

Decoding alone does not establish trust. Use synthetic tokens in the preview. Validate issuer, audience, expiration and algorithm policy in your own application; supported algorithms and key handling need review.

Replace sample business information, configure your own public domain and metadata, and review accessibility and connected services before publishing.
