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.

Tips

Use for Test Tokens, Not Passwords

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

Combine Character Sets for More Entropy

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