AWS Single Sign-On (AWS SSO) now enables you to customize the certificate it uses when you access applications such as Salesforce, ServiceNow, and Microsoft Office 365. AWS SSO uses a certificate to sign and send an authentication token to the applications you access. Through the AWS SSO console, you can now customize the certificate validity period, signing algorithm type, and the key size to match your corporate security policies.
