Which user account is created on Linux while installation? If you created only the root account, read on to learn how to set up a user account. Because your Red Hat Linux system creates one account (the root account) during installation, some new users are tempted to use only this account for all their activities.
What are user accounts in Linux? User accounts provide interactive access to the system for users and groups of users. General users are typically assigned to these accounts and usually have limited access to critical system files and directories. Unix supports a concept of Group Account which logically groups a number of accounts.
What is the default username and password for Linux? For distributions that allow root login by default, such as RHEL, CentOS, or Scientific Linux: username: root. password: fln75g.
How many user accounts can be created in Linux? Theoretically you can have as many users as the user ID space supports. To determine this on a particular system check out the definition of the uid_t type. It is usually defined as unsigned int or int meaning that on 32-bit platforms you can create up to almost 4.3 billion users.
