Data stays on your device — nothing is uploaded.
Build an HTTP Authorization: Basic … header in your browser. Credentials never leave the device.
Enter a username and password, then press Generate. The tool builds username:password, UTF-8-encodes
it, Base64-encodes the bytes, and shows the full header line.
Copy puts the full header (including the Authorization: Basic prefix) on the clipboard. The eye
button shows the password in the field only. The result never prints the password in clear text.
Data stays on your device — nothing is uploaded. There is no account, no save to the cloud, and no credential in the URL.
No. The output is only the Base64 of username:password inside the Authorization header. The password
appears in clear text only when you reveal it in the field.
No. Generation runs locally. Closing the tab discards the fields. Nothing is written to LocalStorage.
No. This tool only generates headers. There is no decode UI by design.
