FAQs
What can I use random strings for?
Tokens, coupon codes, test data, placeholder passwords and any spot where you need unpredictable text.
Are these cryptographically secure?
They use your browser’s built-in random generator — fine for tokens and test data, but for high-security secrets use a dedicated password manager.
Why are angle brackets excluded from symbols?
The characters < and > are left out so generated strings can be pasted safely into HTML and code without breaking markup.
Is my data sent anywhere?
No. Generation runs entirely in your browser and never transmits or saves anything.
