supabase-extract-jwt

You can extract Supabase JWTs from client-side code by scanning frontend artifacts, cookies, and localStorage. This skill automates token discovery, decoding, and claim analysis to surface exposed anon keys, service keys, and user tokens for remediation.

Supabase JWT claims analysis is the process of decoding tokens to inspect their payload data, such as user roles and key types. You need it during security audits to identify exposed anon keys, service keys, and user tokens in client applications.

Yes, you can find exposed Supabase service keys stored in localStorage. This skill scans client storage patterns and code to identify and extract embedded anon keys, service keys, and user tokens, generating evidence-ready output for security audits.

The best way to audit Supabase token storage patterns is to automate extraction from client-side code, cookies, and localStorage. This skill decodes discovered JWTs, analyzes claims, and produces structured evidence for security audits and remediation.

To generate evidence-ready output for exposed Supabase anon keys, extract and decode the tokens from your client app. This skill parses JWT claims and produces structured context updates documenting the exposed keys and their storage patterns.
