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.
