Oracle Cloud Infrastructure Customer,
Security is a top priority for Oracle. To help improve the security posture of your Oracle Cloud Infrastructure (OCI) tenancy, Oracle is taking steps that will require the use of multi-factor authentication (MFA) for all new tenancies. In the future, Oracle will enforce this policy for all OCI tenancies.
MFA helps reduce the risk of your tenancy being compromised by strengthening the authentication process. Along with your username and password, you will be challenged for a second factor of authentication. Oracle recommends using phishing-resistant MFA devices such as FIDO2 compliant security keys for all cloud administrators.
Immediate Recommended Action: Enable MFA for all Oracle Cloud administrators. To set up MFA using Oracle best practices, see the IAM MFA documentation:
