Each user can create 5 keys maximum.
Please do not disclose your key to anybody to avoid asset loss. For security reasons, we recommend that each API Key should bind 4 IP addresses at most. If there is only one IP address, you can enter it directly. If there are more than one IP addresses, you should separate them with halfwidth comma (e.g. 192.168.1.1,192.168.1.2,192.168.1.3).
