API Key Generator
Use API Key Generator to create a strong local api-style key — free, immediate, and with nothing to install. Values come from the browser's built-in cryptographic random generator (Web Crypto), not a predictable pseudo-random function. It is used most by anyone replacing a reused password with something unguessable. Nothing is remembered, so copy the value before leaving the page. There is no account to create, no email to hand over and no cap on how often you use it.
Key features
- Nothing is remembered, so copy the value before leaving the page.
- Uses crypto.getRandomValues — the same source browsers use for real cryptographic work.
- Works on desktop, tablet and phone — no separate app to install.
- Loads in under a second and gives its result in one action.
How to use API Key Generator
- Set your requirements: Choose the length and which character types to include.
- Generate: Press the button — a fresh cryptographically random value appears immediately.
- Store it safely: Copy it into a password manager now. Nothing is kept once you leave the page.
Frequently asked questions
- Can the same value be generated twice? — At the lengths used here the chance is vanishingly small — far below anything that matters in practice.
- Can I recover a value I lost? — No, and deliberately so: nothing is retained. Copy it into your password manager before leaving.
- Is the output from API Key Generator genuinely random? — Yes. API Key Generator uses the browser's Web Crypto generator, which is designed for cryptographic use — not the predictable Math.random.
- Could anyone else see the value? — No. It is created in your tab and never sent anywhere. Nothing is logged or stored.
