An API Key Generator is a developer tool that creates secure, unique identifiers used to authenticate requests between applications and services. These keys act like digital passwords, ensuring only authorized users can access your APIs.

Our generator supports multiple formats—such as ak_, Bearer_, sk_, and pk_—and lets you customize length, character sets (hex, base64, alphanumeric, or custom), and environment suffixes like _dev or _prod. Whether you need a single key or a batch of ten, you can copy, download, or mask them instantly.

Perfect for securing REST endpoints, webhook secrets, micro-service tokens, or any scenario requiring cryptographically random credentials—without storing them on external servers.
