Frequently Asked Questions
What is JWT Token Generator?
Generate signed JWT tokens online for free. Set custom claims, choose signing algorithm (HS256, RS256), configure expiration, and copy the token instantly.
Are generated values truly random?
The tool uses the browser's built-in cryptographic random number generator (crypto.getRandomValues) when security matters, and high-quality pseudo-random algorithms for general-purpose generation. This ensures unpredictable, non-repeating output.
Can I customize the output?
Yes, the generator provides controls such as sliders, toggles, and selection menus to fine-tune the output to your exact requirements. Adjust length, character sets, formats, and other parameters before generating.
How are random values generated?
Values are generated entirely in your browser using JavaScript's native APIs. No external service or server call is involved, which means generation is instant and your output is never transmitted anywhere.
Is JWT Token Generator free to use?
Yes, this generator is free to use with no limits on how many values you can create. No signup or account is needed.
Is my data safe when using JWT Token Generator?
Yes, all generation happens in your browser. Nothing is sent to a server, and no generated values are stored or tracked.
