What is the Random String Generator?
Create random strings for API keys, session tokens, referral or coupon codes, test data and file names. Pick the length, character sets (uppercase, lowercase, digits, symbols), exclude look-alike characters (0/O, 1/l/I) for codes people type, add a prefix and generate up to 1,000 at once. All randomness comes from your browser’s cryptographic generator.
How to use the Random String Generator
- Choose length and character sets.
- Optionally add a prefix and exclude similar characters.
- Generate, then copy or download.
Security tip
For secrets use at least 32 characters with letters and digits. Never reuse API keys across projects.
This Random String Generator is 100% free, needs no signup and runs privately in your browser – on phone, tablet or computer.
