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.

For account passwords, use the dedicated Password Generator, which is tuned for security use.

Enabling more character types increases the randomness of each generated string.
