FAQ
How is an HTTP Basic Auth header constructed?
The client concatenates username and password with a colon (username:password), encodes it to Base64, and prefixes it with the word "Basic ".
Is Basic Auth safe over unencrypted plain HTTP?
No. Base64 is an easily reversible encoding, not encryption. Basic Auth must always be served over secure HTTPS/TLS connections.
Are my entered credentials logged or captured?
No. Credentials are processed strictly in local browser memory via JavaScript, ensuring that no authentication secrets are leaked.
