Frequently asked questions
Is Base64 encoding secure on its own?+
No — Base64 is easily reversible, not encryption. Basic Auth should only ever be used over HTTPS, where the connection itself provides the encryption.
Is my password sent anywhere?+
No, the header is generated entirely in your browser using the Base64 encoding built into JavaScript — nothing is transmitted.
