Token-based Authentication for the CLI

If you're not already familiar with the available credentials, see User Credentials. Each user automatically has the ability to change or reset their own Console password, as well as manage their own API keys. An administrator does not need to create a policy to give a user those abilities. To manage credentials for users other than yourself, you must be in the Administrators group or some other group that has permission to work with the tenancy. Having permission to work with a compartment within the tenancy is not sufficient. For more information, see The Administrators Group and Policy. IAM administrators or anyone with permission to the tenancy can use either the Console or the API to manage all aspects of both types of credentials, for themselves and all other users. This includes creating an initial one-time password for a new user, resetting a password, uploading API keys, and deleting API keys. Users who are not administrators can manage their own credentials. In the Consoleusers can:. Note "Auth tokens" were previously named "Swift passwords". Any Swift passwords you had created are now listed in the Console as auth tokens. You can continue to use the existing passwords. Auth tokens are Oracle-generated token strings that you can use to authenticate with third-party APIs that do no support Oracle Cloud Infrastructure 's signature-based authentication. Each user created in the IAM service automatically has the ability to create, update, and delete their own auth tokens in the Console or the API. Administrators or anyone with permission to the tenancy also have the ability to manage auth tokens for other users. Note that you cannot change your auth token to a string of your own choice. The token is always an Oracle-generated string. Auth tokens do not expire. Each user can have up to two auth tokens at a time.

OCI authentication (Oracle)


Authentication means verifying the identity of someone a user, device, or an entity who wants to access data, resources, or applications. Validating that identity establishes a trust relationship for further interactions. Authentication also enables accountability by making it possible to link access and actions to specific identities. After authentication, authorization processes can allow or limit the levels of access and action permitted to that entity as described in Chapter 5, "Authorization: Privileges, Roles, Profiles, and Resource Limitations". Oracle allows a single database instance to use any or all methods. Oracle requires special authentication procedures for database administrators, because they perform special database operations. Oracle also encrypts passwords during transmission to ensure the security of network authentication. To validate the identity of database users and prevent unauthorized use of a database user name, you can authenticate users by using any combination of the methods described in the following sections:. Chapter 10, "Administering Authentication"discusses how to configure and administer these authentication methods. Some operating systems permit Oracle to use information they maintain to authenticate users. This has the following benefits:. Once authenticated by the operating system, users can connect to Oracle more conveniently, without specifying a user name or password. With control over user authentication centralized in the operating system, Oracle need not store or manage user passwords, though it still maintains user names in the database. Audit trails in the database and operating system can use the same user names. When an operating system is used to authenticate database users, managing distributed database environments and database links requires special care. Oracle Database Administrator's Guide sections on and index entries for authentication, operating systems, distributed database concepts, and distributed data management. Operating system-specific documentation by Oracle for more information about authenticating by using your operating system. Authentication over a network is handled by the SSL protocol or by third-party services as described in the following subsections:. It can be used for user authentication to a database, and it is independent of global user management in Oracle Internet Directory. That is, users can use SSL to authenticate to the database even without a directory server in place. Authentication over a network makes use of third-party network authentication services. If network authentication services are available to you, then Oracle can accept authentication from the network service. If you use a network authentication service, then some special considerations arise for network roles and database links. Oracle Database Administrator's Guide for more information about network authentication. Kerberos is a trusted third-party authentication system that relies on shared secrets. It presumes that the third party is secure, and provides single sign-on capabilities, centralized password storage, database link authentication, and enhanced PC security. It does this through a Kerberos authentication server, or through Cybersafe Active Trust, a commercial Kerberos-based authentication server. Authentication systems based on PKI issue digital certificates to user clients, which use them to authenticate directly to servers in the enterprise without directly involving an authentication server.

OCI Renewal Process


Improved performance and scalability through the efficient use of system memory and network connectivity. Applications that support an increasing number of users and requests without additional hardware investments. OCI enables you to manipulate data and schemas in an Oracle Database using the C programming language. It provides a library of standard database access and retrieval functions in the form of a dynamic runtime library OCI library that can be linked in an application at run time. Use of familiar third-generation language programming techniques and application development tools, such as browsers and debuggers. Connection pooling, session pooling, and statement caching that enable building of scalable applications. Availability on the broadest range of operating systems of all the Oracle programmatic interfaces. Enhanced array data manipulation language DML capability for array inserts, updates, and deletes. You compile and link an OCI program in the same way that you compile and link a non-database application. There is no need for a separate preprocessing or precompilation step. Oracle Database supports most popular third-party compilers. The details of linking an OCI program vary from system to system. On some operating systems, it may be necessary to include other libraries, in addition to the OCI library, to properly link your OCI programs. See your Oracle Database system-specific documentation and the installation guide for more information about compiling and linking an OCI application for your operating system. APIs to design a scalable, multithreaded application that can support large numbers of users securely. SQL access functions, for managing database access, processing SQL statements, and manipulating objects retrieved from an Oracle database. In a nonprocedural language program, the set of data to be operated on is specified, but what operations are to be performed, or how the operations are to be conducted, is not specified. The nonprocedural nature of SQL makes it an easy language to learn and to use to perform database transactions. It is also the standard language used to access and manipulate data in modern relational and object-relational database systems. In a procedural language program, the execution of most statements depends on previous or subsequent statements and on control structures, such as loops or conditional branches, that are not available in SQL. The procedural nature of these languages makes them more complex than SQL, but it also makes them more flexible and powerful. The combination of both nonprocedural and procedural language elements in an OCI program provides easy access to an Oracle database in a structured programming environment. OCI supports all SQL data definition, data manipulation, query, and transaction control facilities that are available through an Oracle database. For example, an OCI program can run a query against an Oracle database. The query can require the program to supply data to the database using input bind variables, as follows:. In the preceding SQL statement, :empnumber is a placeholder for a value that is to be supplied by the application. The applications you develop can be more powerful and flexible than applications written in SQL alone. OCI also provides facilities for accessing and manipulating objects in a database. OCI has facilities for working with object types and objects. An object type is a user-defined data structure representing an abstraction of a real-world entity. For example, the database might contain a definition of a person object. The object type definition serves as the basis for creating objects that represent instances of the object type by using the object type as a structural definition, you could create a person object with the attribute values 'John', 'Bonivento', and '30'. Object types may also contain methods —programmatic functions that represent the behavior of that object type. Oracle Database Concepts. These capabilities include:. For a more detailed description, see "Encapsulated Interfaces". Different types of SQL statements require different processing steps in your program. It is important to take this into account when coding your OCI application. Oracle Database recognizes several types of SQL statements:. Data definition language DDL statements manage schema objects in the database.

Only the user can enable multi-factor authentication MFA for their own account. Users can also disable MFA for their own accounts. With MFA enabled in the IAM service, when a user signs in to Oracle Cloud Infrastructurethey are prompted for their user name and password, which is the first factor something that they know. The user is then prompted to provide a second verification code from a registered MFA device, which is the second factor something that they have. The IAM service supports two-factor authentication using a password first factor and a device that can generate a time-based one-time password TOTP second factor. You can find these apps in your mobile device's app store. You must install one of these apps on your mobile device before you can enable MFA. You can restrict access to resources to only users that have been authenticated through the IAM service's time-based one-time password authentication. You set up this restriction in the policy that allows access to the resource. To restrict the access granted through a policy to only MFA-verified users, add the following where clause to the policy:. To enhance security, you want to ensure that only users who have been verified through MFA can manage instances. To restrict access to only these users, revise the policy statement as follows:. With this policy in place, only the members of GroupA who have successfully signed in by entering both their password and the time-based one-time passcode generated by their registered mobile device, are allowed to access and manage instances. Users who have not enabled MFA and sign in using only their password, will not be allowed access to manage instances. For information on writing policies, see Policy Syntax. After your user name and password are authenticated, you have successfully supplied the first factor for authentication. The secondary authentication page displays and prompts you to enter a one-time passcode, as shown in the following screenshot. Open the authenticator app on your registered mobile device and then open the account for your Oracle Cloud Infrastructure tenancy. The following screenshot shows an example from Oracle Mobile Authenticator. Enter the passcode displayed by your authenticator app for example, and then click Sign In. Important: The authenticator app generates a new time-based one-time passcode every 30 seconds. You must enter a code while the code is still valid. If you miss the time window for one passcode, you can enter the next one that is generated. Just ensure that you enter the code that is currently displayed by your app. After you authenticate, prompts instruct you to return to the CLI and enter the name of a profile. If you lose your registered mobile device, you will not be able to authenticate to Oracle Cloud Infrastructure through the Console. Contact your administrator to disable multi-factor authentication for your account. You can then repeat the process to enable multi-factor authentication with a new mobile device. If a user tries 10 times in a row to sign in to the Console unsuccessfully, they will be automatically blocked from further sign-in attempts. Each user can disable MFA for themselves. An administrator can also disable MFA for another user. Warning Do not disable MFA unless you are instructed to by your administrator. Prerequisite: You must install a supported authenticator app on the mobile device you intend to register for MFA. In the upper-right corner of the Consoleopen the Profile menu and then select User Settings.
