FAQ
Are these real API keys?
No. They are generated token strings. Your app must still validate and store keys securely.
Why use a prefix?
Prefixes make test keys easier to identify by environment or project.
Can I control length?
Yes. Use the length field.
Where should keys be stored?
Use a trusted secret manager or secure backend storage.
