Choose from More Authentication Protocols for Named Credentials
You can now use JWT, a JWT Token Exchange, and AWS Signature Version 4 as authentication protocols to build named credentials for your callouts. These protocols leverage open standards with wide adoption, providing secure access to even more sources than before. Using JWT or JWT Token Exchange, your user’s external service authentication credentials are handled for them instead of relying on users to manually configure credentials. With AWS Signature Version 4, you can perform callouts to resources in Amazon Web Services over HTTP using the Signature Version 4 signing process.
Where: This change applies to Lightning Experience, Salesforce Classic, and all versions of the Salesforce app in all editions.
