Basic Auth Generator

Build an HTTP Authorization: Basic header from a username and password — or decode one back to its credentials.

Basic Auth Is Not Encryption

HTTP Basic authentication simply Base64-encodes username:password — which anyone can decode instantly, as the Decode tab shows. It provides no confidentiality on its own, so always send it over HTTPS/TLS. Prefer token-based schemes (Bearer/JWT) for user-facing APIs, and reserve Basic auth for server-to-server calls on trusted, encrypted channels.
