FAQ
Are the generated API keys secure?
The generator uses cryptographically secure browser randomness to create unpredictable key values.
Can I customize the API key length?
Yes. You can choose the length of the generated key according to your application's requirements.
Can I add a prefix to an API key?
Yes. An optional prefix can make keys easier to recognize by their purpose or environment.
Are generated API keys stored anywhere?
No. The key is generated in the browser and is not required to be sent to or stored by the tool.
Should I use generated API keys directly in production?
They can be used when appropriate, but production API keys should be managed through a secure secrets-management process and should never be committed to source control.
Can an API key be recovered if it is lost?
No. Generated keys are random values and cannot be reconstructed from the tool. Keep a securely stored copy or generate a replacement key.
