Frequently Asked Questions

Tokens or readable strings?

UUID v4 for unique IDs (crypto-random); other alphabets use browser randomness — never use them as security secrets.

How long should the string be?

16 chars for references, 32+ for tokens. Length beats complexity for machine-read values.

Bulk generation?

One string per click — regenerate for more. Copy or download each result for fixtures and seeds.

Do generated strings upload?

No — generation runs locally in your browser. Strings never leave your device.

How do I get a real UUID vs a 32-char API key?

Pick the UUID charset for a crypto-randomUUID v4; the API Key preset mints 32 alphanumeric chars instead. Length runs 1-1,000 with quick-pick buttons at 4, 8, 12, 16, 32, and 64.
