About SAML & OAuth
- • SAML (Security Assertion Markup Language) is an XML-based standard for SSO
- • OAuth tokens (JWTs) are commonly used for API authentication
- • Always verify signatures in production - this tool only decodes, not validates
- • Never share real tokens publicly - they may contain sensitive information
SAML & OAuth - Technical Details
SAML (Security Assertion Markup Language) is an XML-based standard for exchanging authentication data. OAuth tokens (often JWTs) are used for API authorization. This tool decodes but does not validate signatures—always verify signatures in production.
