Acceptance Criteria

When generating a username, there are several guidelines you can follow to ensure it meets certain criteria. Here are some general rules to consider when generating a username:

• Length: Choose a username that is between 4 and 20 characters long. This range provides a good balance between being too short and too long.
• Alphanumeric Characters: Include a combination of letters (both uppercase and lowercase) and numbers in your username. For example, you can use a mix of "a-z," "A-Z," and "0-9" characters.
• Avoid Special Characters: While some platforms allow special characters in usernames, it's generally a good idea to avoid them. Stick to letters and numbers to ensure compatibility across different platforms.
• No Spaces: Most platforms do not allow spaces in usernames, so make sure your username is a single word or utilizes underscores or hyphens to separate words.
• Unique: Try to create a username that is unique and not easily confused with others. This helps to avoid confusion and ensures that your username stands out.
• Meaningful and Memorable: Aim for a username that is meaningful to you or relates to your interests. It should also be memorable for others. Avoid using random combinations of characters that hold no significance.
