Auth Tools

Generate PKCE code_verifier and code_challenge pairs, create Basic Auth Authorization headers, and build OAuth 2.0 authorization URLs with client_id, scope, state, and PKCE parameters.

Auth Tools

• PKCE Generator

  Generate a PKCE code_verifier and code_challenge for OAuth 2.0 authorization flows. S256 is recommended; use plain only when your provider requires it. Leave empty to auto-generate, or paste your own verifier.

• Basic Auth Generator

  Create a Base64-encoded Basic Auth credential and ready-to-use Authorization header. Enter username and password in settings, or paste user:pass in the input (first colon separates username from password). Uses UTF-8 encoding.

• OAuth URL Builder

  Construct an OAuth authorization URL from your provider settings. PKCE parameters are included only when code_challenge is set. Prefer response_type=code; implicit flow (token) is deprecated. Add extra key=value parameters in the input if needed.
