The username you entered contains characters that are not letters or numbers. If you entered a space or a dash (-) you'll probably get this error.
Anything that is a number or a letter is an alphanumeric character, so examples are punctuation and symbols: [, }, ~, /, *, @, and so on.
Any character which is not A-Z or 0-9. Examples of non-alphanumeric characters: !"£$%^&*()
Alphanumeric user name would be using numbers and letters in the name. John1234 is an example. Remember that most naming conventions for websites or even some domains require strong user name/password encryption. And example would be. JohN_1234. Note the use of caps and underscore. This would less likely be able to crack or figure out by an unwanted user.

To create an alphanumeric username, combine letters and numbers in a way that is meaningful or memorable to you. Start with a word or phrase that reflects your interests, then incorporate numbers, such as your birth year or a favorite number. Ensure the username is unique by checking its availability on the platform you plan to use. Aim for a balance between creativity and simplicity for easier recall.
Yes, a space is considered a non-alphanumeric character. Alphanumeric characters include letters (both uppercase and lowercase) and numbers (0-9), while non-alphanumeric characters encompass symbols, punctuation marks, and whitespace, including spaces. Therefore, a space does not fall under the category of alphanumeric characters.
