What Is a Random String Generator?

A random string generator creates one or more strings of a chosen length, drawn from whichever character sets you select — uppercase letters, lowercase letters, numbers and symbols — useful for generating test data, temporary tokens or sample identifiers.

Unlike the Password Generator, which is tuned specifically for account security, this tool is general-purpose — suited to any situation where you just need an arbitrary random string of a given length and character set.
