How to Use the Random String Generator
- Set your desired string length.
- Choose which character sets to include: uppercase, lowercase, numbers, symbols.
- Click "Generate" to create a new random string, and "Copy" to copy it.
Random strings vs. passwords vs. tokens
A random string is a general-purpose sequence of characters — useful for test fixtures, placeholder data, or short random labels. This is different from a password, which is specifically intended to protect access to an account, and different from a security token (like a session or API token), which typically requires specific length, entropy, and generation guarantees defined by the system that will consume it.
Security limitations to understand
While this tool uses your browser's cryptographically secure random number generator, whether a given random string is "secure enough" for a specific purpose (like an API key or session token) depends entirely on how that value will be used, its required length, and the system that will validate it. Don't assume a generic random string automatically satisfies a specific security requirement without checking.

Tips
- For anything security-sensitive, use the dedicated Password Generator or check the specific requirements of the system consuming the value.
- Longer strings dramatically increase the number of possible combinations.
Frequently Asked Questions
Is this the same as a password generator?
It's closely related — both use secure randomness — but this tool is meant for general-purpose random strings, while the Password Generator is specifically tuned and labeled for account passwords.
Can I use this output as a secure API token?
Only if it meets the length, character set, and entropy requirements of the system you're using it with — check that system's documentation rather than assuming.
