EBS r12.2.10 on OCI - Database 19C

Hello,

We need to implement the following two authentication modules on our EBS environment running on OCI.

1. Complex Passwords. Our current EBS users have a very liberal password scheme, which we want to replace with complex password enforcement.
2. MFA. Implement Multifactor Authentication using some Authenticator for users. or use email as a secondary form of Authentication.

Please advise how the above can be achieved.

Thank you
