When anyone registering with a website , it may say " your password must have 8 or more characters and it should be a combination of a-z, A-Z, 0-9, and atleast a symbol. Then what should you do? most probably you have to create a new password to meet with these requirements because you didn't have a password which meets with these requirements.
If you are a Linux user you can use your Linux Command line to create a random, powerful password which can't be guessed by anyone.
First of all you must have "
pwgen" to generate new passwords using Linux Command line. When you type
pwgen in your terminal it should show some passwords which has generated randomly. If it show these message similar to this "
bash: pwgen: command not found" when you type
pwgen, it means you didn't have
pwgen installd in your system. So, use your "
package manager" to install it. After installing pwgen, you can type
pwgen and view some random passwords. You can use
pwgen with some options to meet your password requirements. use "
pwgen --help" to see available options on the command.
This command generates random passwords and you can't see the same password twice by using the pwgen command with the same options.
Here is the syntax you could use this pwgen command to generate passwords.
pwgen [ OPTIONS ] [ pw_length ] [ num_pw ]
- [ OPTIONS ] -means availabe customizations for pwgen. you can use several options at one time, but all of theose options should not be seperated by spaces or something. but when you start using options, it should contain - mark before the first option that you call.
- [ pw_length ] is the character length of the password that you need.
- [ num_pw ] here you can say the number of passwords needed.
when using these options don't use bracket [ ] marks.
