f.You could also choose to “Create by yourself”. Please make sure your private key is sufficiently random. We require your private key to be at least 16 characters long, at most 64 characters long and contain at least one lowercase letter and one number. In theory, any string of numbers and letters can be used to generate your Suter account, even a simple password such as "123456", but this is extremely insecure, please do not do this. For the safety of your Suter account, please keep your private key in a safe place.
