docs: note JWT Trusted Identity Propagation is not supported#716
Merged
Conversation
JWT TIP is exposed only through the Athena JDBC/ODBC drivers and is not available via boto3/botocore. Document this limitation in the Credentials section so users evaluating PyAthena for SSO-driven environments know to either use the JDBC driver or fall back to IAM Identity Center assume-role.

WHAT
Add a "Unsupported: JWT Trusted Identity Propagation" subsection at the end of the Credentials section in
docs/usage.md. Explains why JWT TIP isn't available in PyAthena and points users to either the official JDBC/ODBC drivers or IAM Identity Center assume-role as alternatives.WHY
AWS added JWT TIP support for the Athena JDBC/ODBC drivers (2025), but the auth flow is not exposed in
boto3/botocore, so PyAthena cannot support it. Users evaluating PyAthena for SSO-driven environments need to know this upfront to avoid wasted investigation.If
boto3/botocoreadds JWT TIP support later, we'll expose it viaConnectionand revisit this note.Closes #713
