Frequently asked questions
- What is HTTP Basic Auth?
- A simple HTTP authentication scheme where the client sends username and password Base64-encoded in the Authorization header. Only safe over HTTPS.
- Is Base64 encryption?
- No. Just ASCII encoding of binary. Anyone who sees the token can decode it, so always use HTTPS.
- Special characters in password?
- Yes. Encodes full username:password as UTF-8 before Base64, so Unicode is handled correctly.
