Preface
Preface Two-factor authentication adds an additional layer of security to the login process. In addition to a Red Hat login and a strong password, a one-time code is required to complete the login action. One-time codes generated by an authentication application on a smart phone. Recovery code authentication generates a list of one-time codes that you can use as a backup if your authentication application is not available. Making open source more inclusive Red Hat is committed to replacing problematic language in our code, documentation, and web properties. We are beginning with these four terms: master, slave, blacklist, and whitelist. Because of the enormity of this endeavor, these changes will be implemented gradually over several upcoming releases. For more details, see our CTO Chris Wright's message .
