How to set a strong password?

To set a strong password for a user in Linux, follow these guidelines:

1. Length: Aim for at least 12-16 characters.

2. Complexity: Include a mix of:

   • Uppercase letters (A-Z)
   • Lowercase letters (a-z)
   • Numbers (0-9)
   • Special characters (e.g., !@#$%^&*)

3. Avoid Common Patterns: Don't use easily guessable information like birthdays, names, or common words.

4. Use a Password Manager: Consider using a password manager to generate and store complex passwords securely.

5. Set the Password: To set a password for a user (e.g., joker), use the following command:

   sudo passwd joker
   

   When prompted, enter your strong password twice.

Example of a Strong Password:

• G7!tR3@pL9#xQ2

This password is 16 characters long and includes uppercase letters, lowercase letters, numbers, and special characters.
