About Basic Auth Encoder
Enter credentials as "username:password" and get the complete header — Authorization: Basic followed by the Base64 encoding — ready to paste into a request. Remember Basic auth is only obfuscation, not encryption: always pair it with HTTPS. Credentials are encoded locally and never transmitted by this tool.
