Basic Auth Decoder

About Basic Auth Decoder

Decode a complete Basic Authorization header or bare token into username and password fields locally, then copy individual credentials or a normalized header.

How to use this tool

Paste a complete Authorization: Basic header, a Basic-prefixed value, or a bare Base64 token. Decode it, then copy the username, password, normalized header, or username:password pair.

What to know

Basic Authentication is reversible Base64, not encryption. Treat the decoded username and password as credentials and use HTTPS for authentication requests.
