Generate random API keys and secret tokens for your own projects. When you build a service, you often need a long, unpredictable string to authenticate clients or sign requests, and rolling that by hand is both tedious and risky if the randomness is weak. This generator uses the browser secure random source to produce high-entropy keys, and lets you add a recognizable prefix (like sk_ or pk_) and choose the length so the output matches your convention. Generate a single key or a batch, and copy any of them with one click. Everything is computed locally and never transmitted, so a secret you create here is only ever seen on your own machine, which is exactly how a secret should be born.
