Bulk API Key Generator
Bulk API Key Generator — generated on your device, never transmitted.
Paste into your .env:
Generate as many API keys as you need at once, each drawn from the browser’s cryptographic random number generator. Set the length, add a prefix such as sk_live_ so keys are identifiable in logs, and download the lot as a text file.
Frequently Asked Questions
Is it safe to generate a secret key on a website?
It is here, because nothing is transmitted. The key is produced by crypto.getRandomValues inside your own browser — the same cryptographic generator your operating system uses — and never touches the network. You can disconnect from the internet and this page still works, which is the simplest way to prove it.
What makes an API key strong?
Length and true randomness. Forty characters of mixed-case alphanumerics is roughly 238 bits of entropy — far beyond anything brute-forceable. What matters more is that the randomness is cryptographic: keys generated from a predictable source can be guessed even when they look random.
Should I use a different key for each environment?
Yes. Development, staging and production must each have their own key. Sharing one means a leak anywhere compromises everywhere, and it lets a token minted in staging be replayed against production.
Where should the key be stored?
In an environment variable or a secrets manager, never in source control. Add your .env file to .gitignore before the first commit — once a secret is in git history, removing it later does not un-leak it, and the key must be rotated.
Does this work on Windows, Mac, iPhone and Android?
Yes. It runs in any modern browser on Windows, Mac, Linux, iPhone and Android with nothing to install and no account needed. Chrome, Edge, Firefox and Safari are all supported.
