FAQ

Can I use token authentication instead of TLS?

No, you shouldn't. In tech way, you can of course, but token and TLS are used for untrusted network env. In that circumstance, TLS has higher priority than this. Token can be trusted only under TLS protection.Token can be stolen easily if you send it through a non-TLS network.

Do you support other authentication mechanisms? Such as ak/sk?

For now, no. But we appreciate someone contributes this feature.
