Just like the Administrator in Windows 10, in Linux, there is always an admin user named Root. The concept is the same as Administrator; Root can make any changes to the system, accessing all files, running commands, changing security settings, etc.. It gives you complete access over the system; hence it requires utmost caution. One incorrect command can destroy many files of the system. It is to avoid these accidents in the first place; the Root user is locked in Ubuntu. Normal daily tasks and applications do not require a Root user, like, downloading and uploading from the internet, creating and deleting documents, etc. . So enable the Root user only if some task gets restricted; it is not suggested otherwise. Why would you need a root user in Ubuntu? Some system-specific tasks do need privileges provided by the Root user. Suppose you need to update Ubuntu via the command line; this command does not run as a normal user. The permission will be denied for it. What is Sudo or Sudo commands? Now, do you know how to run commands as Root? We can run commands as Root by adding sudo before commands. Ubuntu, Ubuntu distributions, and Linux distributions use a mechanism for it that is called Sudo. Sudo is a program that manages access to the commands that are being run as Sudo or normal users. Sudo is a dynamic and versatile tool. This is the program that allows a user to run all commands as Root by configuration. This configuration can be selective to allow only a set of commands as root or make it so the sudo can run without any password. As you know when you install Ubuntu you are asked to create a user account that works as admin on your system, as per the sudo policy. The default policy in Ubuntu can run any command on the system with root privileges. Sudo does not even require a Root password, and it works on the user’s own password. Whenever you run the command with sudo it will ask for the user's password. If you run the Su command and do not enter the password, you will come across ‘su authentication failure’. Going back is simple; like any other command, you can go back to the normal user by using the exit command. How to Login As Root in Ubuntu When you first log in to Ubuntu on your PC, it does not enable the Root automatically. It does not even ask for Root user credentials. It will create a normal user, and this normal account will have sudo privileges. This user will be used to run sudo commands to perform administrative tasks required. To enable the Ubuntu root account, you will need to give it a password. To give a password use passwd command. To run the passwd command on the root account, you will need privileges of sudo. Now, how to do that? There are a few steps to do that. First, open the Ubuntu terminal and run the groups by the command “groups”. It will tell you if you have the root privileges or not; if you have them, then set the root password with the following command: “sudo passwd root”. The first command prompts your password to confirm the privileges and the passwd command prompts you, to enter a new password, you have to enter the password two times. Now it is ready to log in as a root user, you can log in by using the su command by typing: su-. After that enter your password, and you are in as a root user. How to login as root in Ubuntu desktop Graphic User Interface (GUI) Now, if you want to login as root to the Ubuntu, there are a set of instructions more to follow and enable the root user: First, open the required path – “/etc/gdm3/custom.conf” and now add AllowRoot that is true under the [security] block, in the following pattern: [Security] AllowRoot=true The next step is to open the path – “/etc/pam.d/gdm-password” , that try to locate the line given below: auth required pam_succeed_if.so user != root quiet_success add it as a comment by putting # in front of the line: #auth required pam_succeed_if.so user != root quiet_success Now you can restart your computer; when you come back and go to the login screen, click on the “not listed?”. The last step is to enter the root user name and password, and you are in. What do if an error comes when loading root? If you get an error while loading root, follow a few commands and open the root profile in a texteditorto rectify it. In the texteditortype - gedit /root/.profile Then find the line mentioned below: mesg n || true When you find it delete and replace this line with the following command. if `tty -s`; then mesg n fi Repeat the log-in process, as stated above.Read More

OK, I don't like long introductions, so here's a list of some of the most important UX tips for creating usable signup and login forms. It is based on my experience reviewing hundreds of beginner designer login flows as a result of my courses Learn UI Design and Learn UX Design. Let's get this party started. The following are some pointers to assist an Interaction Designer in creating better registration and login forms. 1. Specify the value proposition. The last thing users want to do is sign up. Users are generally unwilling to sign up unless they see value in doing so. Filling out the form's value proposition must be clearly defined. Keep the message short and to the point. LinkedIn is an excellent example of this. The value proposition is defined by changing messages. 2. Make it clear where to log in. When a user arrives on the website, make it clear where they can Register or Login, especially if Login is the primary call to action. 3. Show input field If login is the most important task on the website, display the login section first, rather than just the sign in or sign up links, as Facebook and Twitter do. 4. Differentiate Sign in and Sign up Not everyone can tell the difference between Sign in and Sign up right away. Mint is an example of how to display the two in different ways (refer above screenshot). GoDaddy takes a slightly different approach, providing visual differences in button styles, clearly defined headers, and a description of the action. 5. Allow Social Login Users can easily login to your website or app using an existing social account, such as Facebook or Twitter, with Social Login. This feature appeals to users because it eliminates the need to remember another password. Read my previous blog to learn about the benefits and drawbacks of using a social login. 6. Instead of a username, use an email address or a mobile phone number. Do not prompt the user to create a username unless absolutely necessary. By default, try to use their email address or phone number as their username. Users do not wish to consider another name. It is easier to remember their email addresses and phone numbers than a new name. 7. ISD code with mobile login Pre-populate the ISD code based on geo-location or cookie information during mobile registration or login. Provide the option for the user to change the ISD code if necessary. 8. Sign in and Sign up option Provide a Sign-in option on the Create Account page and a Sign up link on the Existing User page to allow users to flip in case they accidentally reached the section. 9. Focus on the first field The form's first input field will be auto-focused. This is only possible on the desktop. This saves the user the time and effort of having to click on the input field. The input field should be highlighted. 10. Keep users signed in Allow users to keep themselves signed in for easier and quicker logins on their personal devices. 11. Remember returning users Users should be remembered and information should be pre-populated. 12. Labels Labels should be top aligned. In material design, floating labels that are short and clear in action are used. For labels, use sentence case or title case, but keep the language consistent. 13. Placeholders Placeholders should not be used as labels. Placeholders should convey a meaningful conversation, such as input format or description. 14. Show password to the user Allow the user to view the password if he so desires. This allows the user to correct any typos in their password. Assure that the password is masked by default. If the user wants to see the password, provide a checkbox or toggle. 15. Alert if Caps Lock is on Inform users if the caps lock is activated while typing a password. 16. Password strength Complex passwords are difficult to crack. Display password strength to allow the user to determine the complexity of the entered password and change it to the desired level of complexity. Display the password policy in an appropriate location so that the user creates the correct password the first time. 17. Error messages Display appropriate and well-defined error messages. Avoid using generic error messages that leave the user guessing. 18. Password recovery authentication Passwords are frequently forgotten by users. Make sure to include a “Forgot password” link to assist the user in resetting his password. Before allowing the user to reset his or her password, ensure that he or she has been authenticated. Some common authentication methods include sending an email or OTP to a registered email address or mobile number, asking recovery questions, and calling a registered mobile number.Read More
